Hi all,I'm new to these forums and have searched as much as possible to get an answer to this but to no avail.I am running XP SP2 on a Mac (not under emulation i.e. Parallels but under Apple's Boot Camp) and FSX SP2 (not Acceleration). So I'm running natively. I'm using a 3ghz quad core with 4 gigs RAM and getting frame rates of over 30fps with Horiaon VFR scenery with all the sliders to the right pretty much. So the machine can cope well.I loaded PMDG747X and everything seemed to load OK. There were no errors or slip ups. Only when I choose one of the base aircraft, the panels are lit up and everything is running. HOwever, half way down the runway, they swith off and I cannot switch them back on again. The auto pilot does its own thing and the stick shudders. I am running the latest update of the software but there is no difference.Can anyone help?ThanksMike
