Hey, sorry to hear it's still giving you trouble. Just out of curiosity, what is your FOV and from what distance are you trying to move the crash bar manipulator? The manipulator logic of X-Plane is sometimes a bit inaccurate if you are VERY close to the object being manipulated, or when your FOV is unusually wide. As a temporary workaround, can you please try binding a pair of joystick buttons or keyboard keys to this set of commands:
tbm900/actuators/elec/emerg_handle_up
tbm900/actuators/elec/emerg_handle_down
These are the commands that the manipulator generates and that the aircraft systems simulation responds to. I hope you don't have any other switches bound to these (especially 2-position switches - not accusing you of being wrong, just some people have seen problems with controls not responding and they forgot they had bound the control to a hardware 2-position switch, so it was keeping the control in the selected position, despite attempts at mouse manipulation).
Appreciate your patience and I'm sure we'll work this out.
