I have this strange problem where some of the switches in the 2D panel become unclickable/frozen. I did the preflight cockpit preperation, take off and climb find. During the cruise quite a few switches and knobs at various points of all the different panels wouldn't work. The cursor didn't change to a hand or +/- or anything. It's like it thought the switches didn't exist any more.

Anyone know a fix for this?
