Yeah, my Logitech extreme3D PRO has a nasty big time spring and everytime Steam does a little update I have to re-calibrate it. I will set dead zone on all axis to 25 and try that, thanks.
EDIT: PROBLEM SOLVED! It was the joystick dead zone. Now AP works perfectly.
cofcorpse THANKS AGAIN for solving this problem!
For your info I have F15c standalone from Steam. I also have over 200 hours in my A10c standalone with no problems with anything.
