Mouse Movement Limitation Bug in 3D-Games (Borderlands, Battlefield etc.)

Hi everybody,
I am struggling with a super annoying bug that makes parallels completely unusable for 3D games to me: In all 3D games I tested so far, mouse movement is limited to the sides, so that you can not turn around completely but are limited to a space of roughly 180° - so you can not turn around completely which makes all 3D games unplayable

Does anybody know how to fix this?
I tried turning of my Magic Trackpad before starting parallels because I assumed this might confuse VM windows, but no success so far...

Thanks for help on this issue,
Florian
