6DOF Camera problem with roll

Hi, i am having problems getting the camera to roll. I have looked at the script and there is $mvRoll global. I created a roll function similar to pitch and yaw that updates the global $mvRoll. I have bound an input to the roll function in the appropriate config script but yet it has no effect. To test i echo the mvRoll variable and it does show different values when tested triggering the bound input. HAving looked at some of the camera code i notice that rotations are performed on the y and x axis so my question is does torque support a 6dof camera or have i missed something stupid. Thanks for any help

Kind regards to you all
