Autopilot will not follow GPS

[petejohno]

I wonder if there is some sort of control binding that's making the switch not move?  This seems more like a JF issue.

Ryan, I tend to agree. the rotary button is stuck on heading. I just tried with the stock gps and it is the same at the moment. I have checked and double checked my bindings and can find no conflict. Even using SPAD.Net, which eliminates all controls from the sim, the result is the same. looks like a JF problem somewhere.
