Hello, I'm on a iMac and for some reason during play my mouse freezes. At first I can only move it left/right and NOT up/down. If I play for a while longer it sometimes stops completely. I can quit the game using the keyboard and eventually the mouse will restore function. Has anyone else experienced this? It only happens in UT and gets very frustrating when I'm up in the ranks and then my mouse freezes and I get blasted. HEEEEELP!
