Re: NVDA sometimes loses control and needs to be restarted
Vincent Le Goff <vincent.legoff.srs@...>
As pointed out, this happened on a lot of computers and with a lot of users. Sure, it could be a hardware problem, but if so, it sounds like the industry may have some important issue. I had this issue with my new laptop when I installed NVDA and there was nothing on the computer, except for Office (which does take some memory). I've had this issue on various computers since then, sometimes older, sometimes newer versions. It honestly doesn't sound like a hardware issue to me. Considering that it has been happening for other users I'd say it's a pretty fair guess.

I find after chewing through some sites that there are some sites that use more memmory than they should or are badly coded and not much you can do about that.
If this is happening generally though, the first thing I'd probably do is check for broken fans and dust.
I'd also check and see what is loaded at startup and what you absolutely need to run in the background, background apps, etc.
Skype, alexa and a few other massive apps use resources like crazy.
In certain situations my system can become quite unstable when I have 1 or 2 or several large apps open for an extended period so I usually don't do this even on my new ish workstation.
You could have a bad drive, I guess, bad ram or though these usually do more than bog the system.
You could have a bad os install, but if windows is that bad constantly it may not be windows.
Of course you won't know till you reformat and reinstall windows however if its being like this, does any other computer in the house do it.
Before fibre it was probably a line issue, I'd also check network and wireless hardware, restart the router, and go to speedtest.net/apps/cli and run speedtest -p no on all connections to get the upload and download speed for each.
Depending what that is it could be the network or wireless channel but unlikely.
My thing would be failing hardware of some sort, check firmware and driver updates and see what we see.
It could also be a slow burn in the cpu or power supply or a stuck fan blade, you need sightlings to look in the box physically but any slow burn could end up with a dead box with no recovery either as a client I had found out the hard way.

Re: NVDA sometimes loses control and needs to be restarted
I have noticed this on a system with low powered ccpu mostly, however you may have a memmory leak in your brouser, and may need to update it.

Re: NVDA sometimes loses control and needs to be restarted

An idea comes to mind as something to try for you. If you are running NVDA stable (2019.2.1, for example), you can do this. I believe it doesn't work in the beta currently.
If you press NVDA+n, p, n, you will be able to remap gestures. If you press M, you should be on "miscellaneous". Expand that with right arrow, and go down to "restart NVDA". If you expand that, then tab to add and press it, you will be able to enter a gesture.
You can use whatever you want, but I used a three finger triple tap to test this. After you perform the gesture, A two item menu appears asking for touch mode. Choose the top one (the one that doesn't say object mode), and press enter. Then tab to OK and press it.
Then, the next time your keyboard stops responding, try that gesture (three finger triple tap in my example). NVDA should restart.
I am curious if that fixes your keyboard problem.
I suspect it won't, but it would be nice to eliminate the variable.

Luke's summary is accurate. I was about to point out that this is not a "lose focus problem", but a "lose control problem" as I put it. Indeed, all the key gestures that should trigger NVDA responses are ignored or handled by the system directly, as they would if NVDA weren't running at all. Reading the previous posts, it seems that my first assertion wasn't too far from the mark: NVDA sometimes "does it" when resources get limited on the system (especially memory), that is when something takes a long time or resource to complete. This doesn't sound like a NVDA issue, rather like a Microsoft issue placing conditions on hooks, but that's just a guess.
Yes, I do use Windows 10. Sorry for not adding this directly in my first message, I didn't think it was relevant. I'm using NVDA 2019.2.1 at the time, not testing the beta just yet, though it's definitely in my to-do-list.

This is NVDA losing the ability to recognize all gestures.
For example, if you are in firefox, an "h" will not take you to the next heading. If you press NVDA+Q to quit NVDA, it will not happen. If you press NVDA+N to open the NVDA menu, it will not open.
Alt+tab will still have its normal Windows application switching effect, but that is not reliant on NVDA, and it doesn't fix anything.
The most reasonable way to fix this problem, is to press the NVDA launch shortcut (usually Control+Alt+N), to restart NVDA.
Gene asked:

Yes, I have only experienced this in Windows 10 that I can recall. Many versions of Windows 10 however, and versions of NVDA going back at least as far as 2019.1 beta, and possibly earlier.

My one experience with one computer where this
happens can't be generalized, but I have one desktop where the keyboard stops
communicating with the machine sometimes. I can unplug and reconnect the
keyboard and that usually corrects the problem. Your machine is evidently
a laptop so you can't do that, of course.
I don't use Windows 10 so I won't describe the
procedure, but you might find it easier and faster to set the on/off button to

NVDA sometimes loses control and needs to be restarted Hi
everyone, This has been happening for some time, on so many computers
and with so many different NVDA versions I can't believe I would be the only one
to see this, and it's not a huge inconvenience, but it's strange and might be
worth looking into. Regardless of the activity sometimes NVDA "loses
control". The key hooks (the NVDA key and all the shortcuts associated
with it) stop working. Using the numeric keypad works as would without
NVDA. Pressing Caplocks, which is a NVDA key for me, triggers the CapLock
function. NVDA still works somewhat and tries to report information, but
one can't open the NVDA menu, read the time, look at the window title or indeed
do lots of things controlled directly by NVDA. When does it
happen? I've tried to reproduce the issue and it's tricky. It never
seems to happen at a given time or in any given application. All I know is
that it seems to "lose control" when a lot of memory is required by other
applications, which creates some kind of lag. So this happens in a browser
when the site has a lot of scripts for instance. This can happen in Word
if the document is long. This can happen while the Windows CLI is opened
and a "demanding" task is running. This can happen when lots of update
information is sent to NVDA (the message queue gets long). It happens more
frequently if the machine on which NVDA runs doesn't have a lot of memory.

Re: curious about NVDA and it's behavior in different browsers.

Sarah k Alawami
Yeah, stop using IE and switch to edge. And then see if the problem is fixed.
Good luck.

Hi list there is something very frustrating that happens from time to time on internet explorer. When I’m on Facebook browsing my notifications from time to time there is one regular poster to one of the groups I’m in who posts these quizzes to the group. They are indicated by a musical notes Icon. For some reason that icon link is broken into pieces. Trying to read the notification when this happens is impossible. That icon was there a total of 26 time. Have done the same thing on chrome and can verify there is only one link there. What is happening and is there anything that can be done to correct this? Am not sure if this is an NVDA issue or a browser issue. Any thoughts. Sent from Mail for Windows 10

Re: NVDA sometimes loses control and needs to be restarted

Sarah k Alawami
I've seen this before. Even narrator loses the narrator key when tha thappens. Saw it with 1903 and 1909 just recently. I had a memmory leak and. a program had crashed and nvda and narrator lost control of their keys. It was odd. Another time I think it just happened out of the blue. I could not get a log because of corse, the nvda key was not working.

Hi everyone,

NVDA still works somewhat and tries to report information, but one can't open the NVDA menu, read the time, look at the window title or indeed do lots of things controlled directly by NVDA.

All I know is that it seems to "lose control" when a lot of memory is required by other applications, which creates some kind of lag. So this happens in a browser when the site has a lot of scripts for instance. This can happen in Word if the document is long. This can happen while the Windows CLI is opened and a "demanding" task is running. This can happen when lots of update information is sent to NVDA (the message queue gets long). It happens more frequently if the machine on which NVDA runs doesn't have a lot of memory. It sounds like a Windows lock, not NVDA's fault, but is there a workaround?

Re: NVDA sometimes loses control and needs to be restarted
Vincent Le Goff <vincent.legoff.srs@...>
Luke's summary is accurate. I was about to point out that this is not a "lose focus problem", but a "lose control problem" as I put it. Indeed, all the key gestures that should trigger NVDA responses are ignored or handled by the system directly, as they would if NVDA weren't running at all. Reading the previous posts, it seems that my first assertion wasn't too far from the mark: NVDA sometimes "does it" when resources get limited on the system (especially memory), that is when something takes a long time or resource to complete. This doesn't sound like a NVDA issue, rather like a Microsoft issue placing conditions on hooks, but that's just a guess.
Yes, I do use Windows 10. Sorry for not adding this directly in my first message, I didn't think it was relevant. I'm using NVDA 2019.2.1 at the time, not testing the beta just yet, though it's definitely in my to-do-list.

This is NVDA losing the ability to recognize all gestures. For example, if you are in firefox, an "h" will not take you to the next heading. If you press NVDA+Q to quit NVDA, it will not happen. If you press NVDA+N to open the NVDA menu, it will not open.
Alt+tab will still have its normal Windows application switching effect, but that is not reliant on NVDA, and it doesn't fix anything.
The most reasonable way to fix this problem, is to press the NVDA launch shortcut (usually Control+Alt+N), to restart NVDA.
Gene asked:
Are those having the problem using Windows 10? I've never had it happen in Windows 7 or XP. Yes, I have only experienced this in Windows 10 that I can recall. Many versions of Windows 10 however, and versions of NVDA going back at least as far as 2019.1 beta, and possibly earlier.

Yep mine’s a laptop. The same thing happens on my tablet, but on that device I can just disconnect the keyboard, which fixes the issue.

I suspect that your keyboard may stop responding. My one experience with one computer where this happens can't be generalized, but I have one desktop where the keyboard stops communicating with the machine sometimes. I can unplug and reconnect the keyboard and that usually corrects the problem. Your machine is evidently a laptop so you can't do that, of course. I don't use Windows 10 so I won't describe the procedure, but you might find it easier and faster to set the on/off button to reboot when you press it for a moment and release it, if there is such an option. ----- Original Message ----- Sent: Tuesday, December 10, 2019 6:51 AM Subject: Re: [nvda] NVDA sometimes loses control and needs to be restarted Hi ☺ This occasionally happens to me as well. It's as if the keyboard stops responding. When this occurs I use the touchscreen to reboot the machine and the problem goes away.

Re: NVDA sometimes loses control and needs to be restarted
This is not the same as NVDA losing focus, and being fixed with an alt+tab. That is an entirely different problem. This is NVDA losing the ability to recognize all gestures.

Re: NVDA sometimes loses control and needs to be restarted
You're not the only one to ever see it. I have had it happen many times, though not even as predictably as yours, and primarily in Firefox. I have always, without fail, been in a hurry, and been unable to take the time to save a debug log to try to track the problem down later.
