It did not happen before, but it is now: my throttle quadrant is not working. Every time I throttle up the plane’s engines do not rev up, and the throttle in virtual cockpit does not move. Oddly, the keyboard keys (F2 and F3) move the throttle. My quadrant is correctly set up in the FSX settings, and I did not pay for FSUIPC (no FSUIPC settings). My throttle quadrant works in X-Plane, the PMDG 737, and the default FSX aircraft. I have my axis set to 2 and inverted in the configurator. My installation is correct (was working a fortnight ago). Any help?
