Yeah, i think mostly the shortcut -type of keypresses get this problem. I have multiple screen setup so i can see is the keyboard shortcuts being deactivated or not. I have the VA always visible. I have commands that will set it -typing mode and typing mode off. Sometimes this happens, especially when doing some editing commands while gaming,- or any other app i use the VA with. Alt tabing the main screen (game screen) on and off, you know what i mean. Then i usually switch the shortcuts on/off manually with mouse. Sometimes it helps, but usually not. If not, then i usually open the editor and the "keypress insurance" -group commands and open the 'missfiring' command(s) and reset. Many times this helps but not every time. If not, then needs to restart VA + everything else.
It's not a huge critical problem, just inconvenient sometimes. In other words, quite annoying lol. I have got used to it, but since it's been this way as long as i remember and with every VA version i have used, i think i should at least mention this here.
