HiI just downloaded the 738/9 package and am having a few problems.Firstly, the yaw dampner will not stay on. I switch it on, it stays on for a few seconds then switches to off.Secondly, the autothrottle will not stay on. I switch it on, the 'arm' comes up very briefly, then it goes back to off.Has anyone got any suggestions?I am not starting from a cold flightdeck, I just load the plane with all engines ready to go.

Whoops. Just found the other thread which discussed the same problem. It didn't show up in search b/c it used the word 'auto-throttle', whereas I sdearched for autothrottle and auto throttle. Doh!Will reply to this thread if I can't solve it.
