Eller testa ngt jag googla fram.
The issue often stems from desktop composition, as far as I know. I used to experience this issue back in Cataclysm when I needed fullscreen mode for Crossfire to function properly.
I assume you're using Windows Vista or Windows 7? If you are, the easiest workaround is to disable the Aero interface while in fullscreen mode. If you're using the 32-bit executable, you can do this simply by right-clicking Wow.exe and going to the properties. In the compatibility tab there will be an option to disable desktop composition. If you're using the 64-bit client, you can still manually disable desktop composition in your visual preferences.
