I have an annoying problem, when trying to play the CoD4 demo and BF2. I have tried everything I can think of and nothing seems to sort it out.

I use a M$ photo keyboard and mouse, however when playing the above games and others mainly fps. As soon as I move the mouse I stop.

Forexample I am moving toward the alley at the begining of CoD4 and I move the mouse to head down the alley and I stop, I press the move forward button, move the mouse and I stop. Anyone got any idea?

I have re-installed the drivers, re-sync' d the mouse and keyboard to the reciever, altered the settings in the mouse and keyboard app, I am quickly running out of patience.
