Mouse problems with Free look while in-Game

Hi guys,

I'm got a problem. For some reason unknown to myself the mouse is not responding for my character for looking around while in game. It does however, work fine when in world editor mode.

i can move my character fine using the WASD keys. So at the moment I have to strafe my character around the map :P

I've checked default.bind.cs in Client to see whats going on.
The mouse is bound as follows:
moveMap.bind( mouse, xaxis, yaw );
moveMap.bind( mouse, yaxis, pitch );

I haven't messed around with the mouse controls in the scripting.

Any ideas what i might have done to my game to cause this problem?
I'm really stuck on this. Any help would be great
Cheers :)
