For about the 6th time in the last couple of weeks I've experience a strange lockup while running both FRED2_Open and FS2_Open. When FS2_Open in full screen everything would go black or close to it (might have part of a window showing) when I closed FS2. I was able to get back to the desktop by hitting alt-f4 a few time thus closing FRED2_Open. The other day it left my screen in the FS2 brightness and moved the whole screen off to the right. Resetting my computer did not fix it I had to go into catalyst control center and reactivate color controls and move the screen back to center. Today I was running FS2 in window mode to try to avoid the problem. It did it again but this time it locked the system up hard. Had to reboot. When it came back up the screen was moved off to the left. Again I had to manually reactive color controls and move the screen back. This is with an ATI Radeon 2900XT and latest drivers. Today it happened in 3.6.10 10-28 build but the other times it was in 3.6.9 TBP build and/or 3.6.10 builds. Any ideas on this one?
