so.... maybe one of you can help me cuz this is driving me mad:
i currently use a logitech mx-1000 mouse - no, its not broken, it works fine in every other program including windows.

before i installed bf2:sf everything worked fine. now i have sf and the latest patches. my left mouse button sporadically ceases to work - which is a real pain in the *** when trying to shoot.  sometimes i have to click 3 or 4 times to shoot, meaning my k/d is sinking rapidly.... :-(
am i the only person expiriencing problems like that? i've already tried disabling software in the background and things like that. anyone have any ideas? (other than driver updates or the likes.....)
