this seems to have ben a oneoff, a fluke if you will, but have a look at the #NVDA error I got when trying to do insert q then telling it to restart NVDA.
Error dialog Couldn't terminate existing NVDA process, abandoning start: Exception: [WinError 5] Access is denied.

Ok, late response - but did you work out what happened? I'm not sure myself offhand, but if it hasn't happened again, that is good and likely, as you said, a fluke.
