Hi,I just purchased the PMDG 747 and I've been trying to get to know the cockpit and I don't know if its me or the aircraft but when I try to switch a button it only goes left or down. For example, on the autopilot altitude hold I can not increase that number it only goes down. Same with vertical speed, heading, and auto throttle. When I try to move a nob to the right it only goes left. For example, I can only turn the APU to off and once its on off I can not move it again. Is there a setting to change this?-Tom

Try using right clicks, I don't have the queen but this question comes up often enough that I know the answer.
