Fsx locks up when I alt tab to the desktop.Another problem I am having is fsx pauses a lot to load scenery settings.I have 2gb of system memory and a geforce 6200 Turbo cache video card 512 MB. I am using the latest nvidi vista drivers.

I think that's normal. Hold Ecsape key to get back FS.Some scenery loads can take a long time. I defragg every week.Do you defragg? That might help.CheersPeter Sydney Australia

Yep, I count myself lucky if I get through a flight these days. I change to window view rather than full screen before accessing other applications on the desktop. I think it helps a little.Cheers,Noel.

Thanks I will try suggestions about getting back from the desktop.As to the frequent scenery loading I am talking about the frequency of the scenery loading sometimes I just get in the aircraft and attempt to change freq on the radio and the sim stops and loads the scenery again. This happens during normal flight also.

Hi Rich,I had the same problem, and it was something related in the FSUIPC in miscellaneous tab to synchronize with real time, uncheck this one, and that will fix it. It did it for me.Hope this helpWalouigi
