I have asked this question on the official Majestic forums, but have not received any answers yet. After reinstalling the dash in P3D 3.3.5 after being away from it for a while, I noticed a minor issue. I have to buttons on my joystick that I use for the elevator pitch trim. They are now also mapped to the autopilot pitch wheel which makes manual flying with the F/D a bit challenging. 

I did try read through some of the documentation, but did not quite understand how to fix this. I would like to change the controller setup so that those two buttons does not control the autopilot pitch wheel. Could anyone tell me how to do that? I´m using the latest versions of the pro edition.

Guessing you're using 125 Hz controls? Sounds like you've got duplicate button assignments in P3D and MJC84.ini, have a look in the ini file for any AP or trim references, they should be under [JOYSTICK_INTERFACE_ASSIGNMENTS]

Thanks, found the ini-file and deleted the entries.
