Yeah I had that problem too, just go into ut, go to the Mod menu. Then there are like...tactical ops options. I think it is either some sound debugger...or something about crosshairs in there. I don't know the exact option..but try experimenting with them. I think there are only 5 things. This ISN'T the keystroke setting thing, nor is it the weapons one. I haven't played in a while so i don't remember...just experiment.
