Re: multiple instances of NVDA

Ralf Kefferpuetz


I currently use latest Win10, Version 2004 (OS Build 19041.450) together with NVDA 2020.2. But again, I have that kind of behavior since years independently of the version of Win10 or NVDA.

I can’t reproduce it on my virtual machines running Win10. Until last week I had the same issue on my Dell company laptop but since last week our corporate IT policy updated our OS from 1803 to 1809 I can’t reproduce it anymore.

It doesn’t bother me at all, I just brought it up since another user of NVDA mentioned the same behaviour. It must be something special on my PC. I will create  / test a new user to see if it is something with my profile….

I just tried and when I press CONTROL+ALT+N, the copy of NVDA which started automatically on login exits cleanly and the new copy starts.  What version of NVDA and Windows are you using though?


I am using Windows 10 (64-bit) Version: 1903 Build 18362 

Running NVDA version: alpha-20763,1ef4dfb0 


That's probably not the most usual combination though (My Windows 10 keeps hitting an error updating and I haven't taken the time to reformat it).  So if you're using a different version of Windows and / or NVDA your mileage might vary.  If anyone else tries this, please do share your version of Windows and NVDA and whether NVDA restarts cleanly or leaves an icon in the notification area.

I should have added that I am using Windows 7 and using NVDA as a portable

I've never had it happen when I unload NVDA, then restart it.  I'm not
talking about using the control alt n command when NVDA hangs or crashes.
I'm talking about using NVDA key q, then restarting.

KI've only seen this happen when NV
DA crashes and I restart it.

Interesting, I regularly restart NVDA and I don't recall ever seeing it from
that.  Do you have any add-ons?

I'll get you one, but I must say that I have rarely NOT had this happen when
doing an NVDA restart.
It is just the way of things.
Since it happens on all of my systems, I assumed it was an error with slave
helper, and couldn't be avoided.
