Rhino freezes on secondary monitor (Problem with the Nihimic audio driver on the motherboard)

OK, one thing you can try is to make a new user and see if things handles differently there. I had some issues with my windows10 a few years ago and before I did a full reinstall I checked and got confirmed that a new user did not have the issues I had. (So it might be worth as a shot in the dark, to check at least, while you wait for a fix :slight_smile: )
Good luck!
