This started just today. I start up the game and get about 5 minutes (or less) in when the screen flashes to black, then after a moment minimizes itself. However, while looking at my desktop with the minimized GC3, the mouse (which can move freely) can't interact with anything for the next several minutes. Once keyboard functionality returns, I can bring up Task Manager, which shows that is GC3 is "running" (rather than not responding). Maximizing GC3 from the task bar brings up an entirely black screen, but with the music still playing.
Is this happening to anyone else? Anyone have a clue as to what is going on?
