I'm not sure I fully understand you, but you're saying that when you start the game the mouse goes crazy? Do you have any gamepads/joysticks plugged in? If so, one of them can control the mouse, and it might be what's giving you trouble.
It was a stupid report from me, because it was obvious that it depends on my system and drivers or what ever (the bug appeared in the menu) ... I've really no idea, why this happened with your program - but when I tried it again now, it worked
