There seems to be a bug that has inverted the forward, and backward mouse controls.

When I push forward with the mouse, the nose of the helicopter moves up, instead of down like it should. When I move the mouse backwards, the helicopter nose goes down. The left/right mouse controls work correctly, the "W,A,S,D" keys are all also working correctly.

My mouse has no issues, and is working correctly with all other controls in the game, it's only the forward, and backward helicopter mouse controls that are inverted. I don't have any issues with any other games, or applications.

I have seen a number of other people say they are having the same issue.

The mouse I'm using is a, CyberPowerPC Standard 4000 DPI with Weight System Optical Gaming Mouse
