Just throwing an idea here, but shouldn't NVDA be able to reach
Windows to tell it "no, keep running, we're still doing stuff"
when pressing the Braille panning keys? I guess most of us don't
notice, because this is triggered by input devices (keyboards or
mouses) but a Braille display just doesn't count. However, I
would think NVDA could do that fairly easily. Just a guess here,
something worth implementing IMO.

Yes, I’ve hit this as well. Just make sure
the power plan is high performance, or that nothing can cause
the computer to sleep. If the screen saver or sleep activates,
then this would occur. The bigger problem is that you cannot
get braille on UAC or log on screens reliably, and that
braille support is fairly crippled without the braille
extender add-on for most braille displays as compared to other
screen readers. However I’m a primary braille user, though I
never use braille input because the translator lag makes touch
typing quicker, even though I have to pick up the keyboard to
do it. Having to install add-ons for braille seems very silly
indeed, as I’d think for those that have displays since a lot
of us prefer braille to speech anyway, that seems like a basic
feature. I’d say for serious braille reading though, braille
Extender is a required install. The key commands are a bit odd
compared to other screen readers, but they work well.
Incidentally the same problem happens with braille on iOS. If
you stop moving your display or something for a few seconds
it’ll disconnect. I’m not sure what the best way should be to
handle this by default though.
