Hi,
I have FSX on Windows 7-64 and sometime last week, I was surprised by an autopilot disconnection after using the button programmed for elevator trim down. Testing with other aircraft, I found that default aircraft are not affected by this issue, but the PMDG 737, A2A C172 and C182 are.
Changing the buttons for others, the same issue continued. Turning on the AP and moving the trim wheel with the mouse, the AP disconnects. I swear that in more than 25 years of MSFS I never saw this behavior.
May I ask now, is this behavior normal?
As I can remember, I did not change anything referenced to buttons, joysticks or pedals. I was mostly flying the PMDG 777 with FS2Crew successfully. The only new fact was the purchase of Alabeo Saratoga + Flight1 GTN750.
I use FSUIPC 4 commercial for all my buttons associations.
Thanks for your attention
Heron
