DO12 - Crash because of "don't know"

Hi there, DO crashed on me although I did nothing spectacular, I was pressing CTRL-0 or CTRL-Mousewheel (over the viewer pane ) while trying to get the DOSV plugin to change it's font settings, I don't know wether activities I did seconds before had any influence, messing with CTRL was the last activity I remember, then the crash dialog poped up.

Maybe you can work out what the cause was. This is v12.1.1, thanks! o)

The crash is coming from dosv.dll, not from Opus itself. That's all I can tell you without source code & debug symbols for dosv.dll.

The exception itself seems unusual as Visual Studio doesn't recognise it or provide a description for it.

Ok thank you!
So it's something for gdobin to investigate! o)
