Rudder Calibration/Logitech Force 3D and FS9 (patched)

Hello, noob here. I've been reading the rules/stickkies etc. and this looks like it's going to be a fine place to come.I hope someone may be able to help me solve an annoying problem.I have a Logitech force 3d joystick which I use with fs9. The problem is in the calibration of the rudder and I'm not sure if it is fs9 specific or I have a dodgy unit. During calibration the needle jumps wildly at the slightes touch of the joy handle. Twisting the handle to left rudder only moves it 2 calibration units where twisting it to the right it flashes all the way to the stops. I have been to the Logitech forums and a couple of other people are experiencing the same behaviour. Although, not as pronounced as my unit. Has anyone out there in fs9 land encountered this and found a solution. Oh God, please let it be so. I am at the stage of threatening it with 'John Cleese fist shakes'.Jon
