Re: Intermittent lack of feedback in Windows Explorer

I've been having this happen for the past few windows 10 and NVDA builds.

It seems to really occur when copying, moving, or deleting files. Sometimes tabbing through the explorer window helps, sometimes a restart of NVDA is required. And when this happens it almost always breaks alt tabbing.

Yes but this is windows 7 too.
 I am as you will see also having windows lock ups on two 7 machines and the only thing in common seems to be something to do with usb, but the add ons have been here for ages so its either nvda or a driver they updated about a few weeks ago, Intell I think.

Hi,

Yes, I thought so. I’m hoping that there would be a resolution from both NV Access and Microsoft (a little hint: some of you are already testing a potential fix).

Cheers,

Joseph

It's build 1803, no insider build.

Hi,

For Windows 10, this is build 17134, correct? If what I’m thinking is happening, then there might be some hope (later).

Cheers,

Joseph

Hi Joseph,

happens on Win 7 and 10. I could detect no correlation with restarting NVDA.

Best,

Felix

Hi,

And does restarting NVDA resolve the problem for a while? If it does and if the problem happens again, then I think I know what might be going on. Also, which Windows version are you using?

Cheers,

Joseph

Hello,

no, the issue cannot be described in terms of delays. When feedback fails to occur, it will then simply not occur no matter how long I would wait. It is genuinely different behavior rather than just slowed down normal behavior.

Best,

Felix

When cursoring up and down, does the selcted item  get said after a delay,
and if so and you hear that, can you then select the file?

I had this with explorer both on windows 7 and 10, and it was the processor
in the  computer actually not running at full speed. It seems on many
laptops the processor is slow to catch up with demand and hence the actual
selection is behind the  one you think it is on, or worse, on nothing at
all!
I'm sure somebody else will respond but I had to go digging into advanced
power management and crank up the idle speed to at least 50 percent, it was
set at 10 percent, before acceptable results occurred.
Of course it could be something else, but this was the reason I found for
most of it. I would have thought that as nvda is hogging one core and hence
stopping the machine using it, Windows ought to sense it and up the speed of
the cores. It seems that this only happens sometimes when more than one core
is maxed out. I guess this might be because nvda is a 32 bit app, not a 64
bit one with  the ability to  push threads though different processor cores.
I'd welcome some more knowledgeable people to comment.

Subject: [nvda] Intermittent lack of feedback in Windows Explorer


Hello,
I'd like to ask around if anyone else has noticed this disturbing trend:
When pressing enter on a folder in Windows Explorer, NVDA usually
announces
"element view list" followed by the name of the first element in that
folder. Often, however, NVDA remains silent. Requesting developer info for
the navigator object then yields something like the log excerpt I am
posting below.
Any ideas how I could make this behave? Being a child of the age of DOS,
when there is silence I usually wait because I assume my command takes
longer to complete. I know I'm pedantic, but then this is software and
not,
say, astrology.
Here is that log excerpt now:
