Congrats to the team on the release of FS 4.
I am experiencing a problem with flap operation on the C-172 and King Air when starting at the end of the runway in ready to fly configuration. The flaps are preconfigured fully down, but I cannot seem to retract them either on the ground or once airborne using the keyboard shortcut (which I left to the default SHIFT-F) or the controller button I configured, or even by manually adjusting the flap control in the aircraft using my mouse. When I'm in the control setup screen, the flap controls are shown as working.
I'm an experienced FS 2 user and have never had this problem. What am I missing?
