Hey everyone,I am having a problem with the autopilot. After I do my FMC, and setup everything, I Takeoff, then Turn on:CMD AFD: ONA/T: OnVNAV: On (Sometimes off if ATC wants me to do something different)LNAX: ONAll goes well, until I alt tab. After I alt tab, and come back to the game (say 30 seconds), the A/p Is disconnected, the plane is headed for the ground, doing around 450 knots.I am currently using service release 1.3 I used the checklist of avsim, but I think I might be missing something, as in pilot error ;-)I Wrote PMDG about this, and they said it was pilot error, but didnt really offer any advice on what I was doing wrong.Anyone know of this problem?Thanks!

I cannot find a function for ALT-Tab in my FS keyboard commands.On my system, using ALT takes me to the full-screen menu bar, and then Tab takes me right back to FS.What were you trying to do with the ALT-Tab command?

Your not knocking your joystick/yoke accidently and disconnecting the AP?..I dont know if it still sends inputs out of FS...

I know this sounds trivial, but are you hitting the "a" key by mistake?- John
