I'm using the provided binary for Mac. Sometimes in the middle of a mission i will have to go back to my Desktop to take care of some business. I go to the game's Options Menu, and untick "Full Screen". When i get done with the OS, i come back to my game and retick "Full Screen". The game makes the conversion to full screen, and i'm unable to move the cursor after that. As far as i can tell, it froze. This is very repeatable. Details: OS 10.4.11 on a G5 PPC with 2 GiBi RAM, both Desktop and UFO screens are set to 1024 X 768.
