Thanks for the good link. Interesting information, but I don't thinks that's my problem. I did a little digging and found the advanced manual and the ini file. So I think I had it. Not quite
When I press the left auto pilot button using the mouse, I get this entry in the log:
811844 *** EVENT: Cntrl= 72123 (0x000119bb), Param= 0 (0x00000000)
The file contained a section for my 747. I added the last line. The complete section is this:
[buttons.PMDG747-400 UNITED AIRLINES]
0=P0,6,C66587,72120
1=P0,8,C66587,72119
2=P0,13,C66587,72111
3=P0,11,C66587,72112
4=P0,10,C66587,72105
5=P0,12,C66587,72104
6=P0,2,C72123,0
I saved and closed the ini file, restarted FSX, and got this in the log.
The log showed:
32313 Aircraft="PMDG747-400 UNITED AIRLINES"
32313 [buttons] now aircraft-specific:
32313 1=P0,8,C66587,72119

It's not reading my entry or doesn't like it. Is there a parameter that I have to increase to say there are seven entries? I've also turned off the programming of the button by FSX itself.
A unrelated bug I got while trying to figure this out was that if I left the 'Send to console window' option checked when I exited FSX, the main window wouldn't display when I selected the saved flight and clicked 'Fly Now'. If I clicked alt-enter to go to full-screen, it would appear on the second monitor. I could then move the display back to the primary monitor, but the window for the CDU no longer functioned. Turning off the 'Send to console window' option, exiting, and reentering FSX fixes the problem. I suspect this is a PMDG problem, but I wanted to ask here as I figured fellow PMDG uses may have come across it. I'm running Windows 7 64 bit with FSX Deluxe, SP1, and SP2 installed.
