Major mouse issue... please help

[treblesum81]

Ok, so when I place my windowed game on my #2 monitor, my mouse seems to go haywire... if I'm in normal point and click mode, everything is fine, but if I got into mouse look mode, it will only turn to the right and move up, it won't move left and it won't move down either. This only happens on the #2 monitor, not the #1, so I actually have to alt tab out of the game, move the window to the #1 monitor and re-enter, which would be fine, except that I always play every game I have on the #2 monitor since there is no task bar there to get in the way or get blocked.

Has anyone experienced this at all? If so, what is the cause of the problem so I can fix it as soon as possible.

Thanks

PS: if this is new and weird, please help me figure out what might be going wrong, since this is the only program this has ever happened on, and even the first time I've seen it happen with this one, as I used to play this game on #2 all the time...
