Re: Intermittent failure of focus in Explorer

Hi,

Pretty sure it isn't jaws. Machines without jaws are doing it just as bad over here. It's especially apparent on lower specked machines with intel atom and celleron processors. It has gotten just a tad better in version 1809 on higher end machines but it is still a huge problem that I hope is addressed soon.


Copying files from one place to another or deleting files should not result in NVDA refusing to read the contents in the explorer window. I'm honestly stunned that this has been going on for this long.

Hi!
It's unlikely that the accessibility driver installed with JAWS has an
impact here, as this is no longer an interceptor but rather a mirror
driver.
Then again, software being software, anything is possible.
Best,
Felix

I have a JAWS demo on my machine. We need to find out if there is a ppattern regarding JAWS.

Well when I open a folder, assuming there are files in that folder, it
normally will say the name of the folder and usually the file. It has
recently seemingly got worse atdoing this.
Far worse, but I'm now wondering if it might be something I noticed in the
programs loaded into the display driver chain.
I did around the same time install Jaws 2018, and although this is Windows
7, I notice it has added a tiny driver of some sort which is there even
when jaws is not running as a process. Sorry cannot recall its name. If that
does take some significant time or change what is getting to nvda it could
be a factor. I mainly only use Jaws for alexa as it works far better than
nvda in that application.

I'm not sure what you are describing. Often, in Windows 7, even with old
versions of NVDA, when I open a folder, nothing is spoken automatically,
such as the first item in the folder. If I move or use speak current line,
what I move to is spoken but I don't know if that is what you are
describing.

Windows 7 does not use UIA though which was why I specifically mentioned
it
here.
I think its simply missing something, as its not every time, only
sometimes.
Its only started to happen recently say in the last couple of releases of
nvda. I guess it might be that the system has to decide if its uia or not
which might stop it getting the info from windows if its significantly
slower than it used to be. My machine is still the same though, so unless
something I installed is doing tit , I'm at a loss.

Hi!
It's a long-standing issue. I reported it at:
https://github.com/nvaccess/nvda/issues/8389
It's probably UIA-related. On Windows 10 build 1809 I haven't seen it
thus far, so it may have been solved there.
Best,
Felix

This is Windows 7, and only seems to have started to happen recently.
I have had a short cut to the root of drive C: on my desktop, but it
can
happen at any time in opening drives or folders, where the actual
focused
drive is not spoken by nvda. Here is the log file. Its not very long. I
select the shortcut with L then hit enter wait and nothing is spoken
then
I
did an nvda/f1 to see what was going on. there is an exception and
nothing
gets focus.

any
light on it, be my guest. It has been fine.
