Mouse going off game screen.

[Flanelman]

Hey guys, so I have an issue while playing Verdun (and so do others but we couldn't find a solution on steam) where, if i say turn left or right, the mouse will continue off the screen, so when you left or right click to aim or shoot, it minimizes the game because you end up clicking the desktop on a different screen?

If anyone can help resolve this I would appreciate it very much, cheers!
