After iam playing 5-10 mins the Game is switching to the Desktop and i can not open it again.
I did try everything with ALT TAB or other things.
The game is still running in the background and its also working if i alt tab i can hear the the menue and stuff if i press buttons on keyboard but it stays minimized.


GPU: GeForce GTX 970
CPU: Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz
RAM: 8.00 GB
System running Windows 7 Home Premium

Is this happening specifically in menus/inventory, or is it at any time?

I would say uninstall and reinstall the game if nothing else fixes the issue.

Worked now out... game borderless and without nvidea hair works and mouse hardware enabled.
