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.

Subject: Re: [nvda] Intermittent failure of focus in Explorer

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.

So has any other windows 7 user got this issue? Also if anyone can shed
any
light on it, be my guest. It has been fine.
