Re: NVDA sometimes loses control and needs to be restarted

I often experience this using Outlook 2016. ALT Tab helps but it is truly a nuisance.

I encounter this problem using Word, the slack application and sometimes thunderbird.

I am testing the NVDA 2019.1 beta 1 version and could not encounter this problme so often for now.

But I need to test a bit longer in order to find out if it occurs.

Other thing: in the NVDA beta I have no add-on enabled.

I am also using Windows 10.

Are those having the problem using Windows 10?  I've never had it happen in Windows 7 or XP.

Hi Vincent and others,

SMILE I hate to break your heart, but you're not the only person this
happens to. I was very glad to see your message and know that I'm not
the only one it happens to. It is a fairly easy fix as you said, but can
get to be a bother and you're right, it does seem to happen when I'm
trying to do multiple things, but it can also happen when I'm just in
the middle of an email. My husband thought it could be TWBlue instead of
NVDA as that program does take a lot of resources, but I unloaded TWBlue
and was still having problems, so I'm thinking as I first thought that
it's something with NVDA and hopefully it will get fixed in the next
