This is 100% because of the calibration of your joystick
Please calibrate it correctly and your issue will be fixed.

I recalibrated my joystick but it had no effect - same thing happens.
I think this is a more complex issue, it happens when the plane is running on autopilot and the the joystick is inopertive. But trying to recover manually with A/P off doesn't work.
It also never happens with the default set of aircraft that come with FSX-SE.
Could there be a conflict with cfg file?
I added a callouts sound modification to the the standard B737-800 and that caused exactly the same problem. Deleted the mod and back to normal.
It's so disappointing not being able to use addons as they offer a lot more functions.
Can you offer any further explantion please? Thanks
