My old Siderwinder Precision 2 Joystick calibrates fine in game, but as soon as I launch a mission the ship spins constantly to the right and I can't stop it. Joystick is working fine in both WC1 and 2. Any idea what's going on and how I can fix it?

I know it's for the xbox 360 controller but it may work

Thanks to both of you- fortunately it was as simple as turning off the mouse in the options menu!
