I am having a problem calibrating ailerons and elevators in FS9 with FSUIPC 3.98. I have tried both my Saitek pro Yoke setup and Saitek X45 with the same end result. I know FSUIPC is seeing both of these controllers because the values move from -16.... to 16..... in both axis assignment tab and joystick calibration tab for elevators or ailerons. The problem arises when I attempt to set min max and center levels. FSUIPC seems to accept the first value i input (either min or max or centre) however further attempts to click on min max or centre max result in the "windows ping sound", and the software will not input the value into the desired min, max, centre position. When i return to FS9 elevators, and ailerons either do not function at all or will respond to one input (Max left or right) (Max up and down) . All throttles, prop feathers, mixtures, rudder pedals and buttons calibrate and work flawlessly. Just the ailerons and elevators seem to have a problem. I have set FS9 to options\ Controls\ Disable Joystick before using FSUIPC . These controllers worked fine before I installed my registered copy of FSUIPC. Any insight would be more than valuable.
