Does it do it while the game is playing, or when you run the launcher?
If its when you start the game up check your resolution settings to make sure they are set the same, you may even want to try deleting it from the system.ini file i think it was. I remember having an issue like yours, but only when trying to launch the game years ago before I realized that was the cause.
