Re: NVDA still freezing, don't know what the deal is


Sharni-Lee Ward
 

It just happened AGAIN. This time, with no Braille Display plugged in,
but still in Word. My sister described what she saw as "It's circling
and the screen is foggy," so I'm assuming it was hanging. It took longer
than normal to shut down, and longer than normal to start up properly,
and apparently Windows Explorer lagged for a few seconds. I don't know
how to recover my writing (I tried one of the previous times this
happened by restoring the auto recovery file from the Recycle bin but it
didn't work...).


Anyways, here's the log. I hope this time I can get an answer for why
this is happening. I'm getting seriously concerned at this point.

Just tried another thing that consistently got NVDA to hang recently,
namely, opening the sounds manager in Control Panel and then arrowing to
the Sound Scheme tab. I thought it only did this because of the Braille
Display but I wanted to test it to make sure. This time, once the window
was closed, NVDA started responding again. I also tried to activate
Narrator but it didn't work, though as I said, that didn't end up
mattering. Here's the log for that session, though I warn you, the
warning repeats itself several times. In case each warning was subtly
different, I copied the whole thing. Don't worry about the Braille error
that shows up first—that's about me starting up the computer and by
extension NVDA without my display plugged in and then saving the
configuration with default as No Braille.

Because if so, I can just change the configuration so I have to connect
it manually when I want to use it, which isn't a problem as I usually
have to re-activate the Braille settings if I have to disconnect the
display for one reason or another, or if the computer's put to sleep. If
the fix is implemented next release, I'll adjust the configuration
again. If it does happen again despite this measure, I will try Gene's
method, although I suspect it will be fine. Thank you everyone for all
your help and tips, and at least I know how to retrieve old log messages
now! :D

Hi there: Do you think your computer could have mellwhere to cause this
freezing?

Why wouldn't my workaround accomplish the same end but more easily.
Because most of the keyboard is frozen when this freeze happens. The
only
thing that works is the windows key and some function keys.
