After purchasing and loading the REP version of C172, I find that the throttle quadrant controls (mixture and throttle) move about half way and then stop and will not move again. I can still use the mouse to operate them. If I load a different plane (e.g. Airfoil Labs C172) the throttle quadrant works fine.
This is very disappointing after spending US20 on the REP version and should have been picked up in your QA checks.
I am working on the latest iMAC 27 in and attach the log.txt file.
