as you may see in the headline, the game shootmania minimizes on its own randomly while playing.
When trying to maimize it again, it's just not working.
I can see the ingame mouse cursor and hear the sound of the game, i can even move and shoot while still seeing my desktop. Shootmania is the only game which does that kind of weird things.
I nearly tried everything like updating my videocard drivers with whql certified ones and betas, reinstalling my videocard, changing the video settings and even installing older drivers which all did NOT help.
Any other ideas to solve this problem are appreciated
I'm using
Windows 7 64 bit Professional
Geforce GTX 260
Intel Q9550 Quad Core@3,4 GHZ
4 GB Ram
If any further informations regarding my system are required feel free to ask.

thx in advance
