Definitely something to fix! I should've known this was a problem, because it's actually an underlying engine issue and even impacts REXPaint! I had someone report this for REXPaint before, and it has been on a future TODO list, but I never did get around to it yet.
Hilarity that REXPaint requires an audio device aside, this should definitely be fixed for Cogmind!
Not a serious bug so it can wait until the next release, but something that needs to be addressed. Thanks!
