Hey all, had a quick question. I have Win 7 with XP mode running rebellion. The game runs fine, but sometimes when I try to enter a space battle (like if I'm not sure of the outcome) The whole screen goes black like it's frozen. After awhile I'll hear the audio of the fleet coming in, but nothing changes on screen. I usually have to close the game down and lose whatever data I hadn't save. Just wondering if anyone had any thoughts.
