Iv tryd, both windowsmode and fullscreen. My mouse moves over in to the second screen and makes the game mouse inactive ingame, I have to move my back my mouse to the game screen to be able to even do anything. In windows mode it just moves from screen one to screen two. in fullscreen it minimizes the game when my mouse gos over to the other screen. There have been an windows update so im not sure what has happend. but it makes the game unplayebal.
