I have been playing the download version of CMSF for a few days now and have run across a problem.
If during the game I use ALT-TAB to escape to the desktop everything appear ok. I can launch other programs and return to CMSF with no apparent problems.
However when I finally exit CMSF the mouse moves normally and has the normal arrow cursor but if I click on the start button or click on a desktop icon to launch a program nothing happens except the mouse cursor may turn into the hourglass cursor.
In any case I cannot get anything to execute once exiting CMSF. I cannot even ALT-TAB-DELETE to the task manager. The only thing I can do is power off the PC and reboot.
This problem ONLY and ALWAYS appears to happen if I ALT-TAB while in game.
My system specs:
Dell Dimension 8400
P4 3.4GH, 2GB RAM
Windows XP Home with SP2
Nvidia 6800GT, forceware 93.71 drivers
