Your screen shouldn't stay black at the end; I had the same alt-tab issue without the black screen but never considered it much of a problem. Dunno if he's going to patch it or not.

I have a related problem with my nVidia laptop display. I _have_ to play in windowed mode because in full-screen mode the game just hangs there with a black screen, even if I try and alt-tab back and forth.
