I have recently installed Windows Vista in the hope that FSX would be more "friendly" but I find thatit locks up after about 1-2 minutes flight. I have tried my settings and default settings but to no avail.I also have FS9 running on Vista without any problems If anyone can offer some advice I would be most gratefulMany thanksGeorge

Just a guess here, but maybe it is a permissions issue with it accessing the 'net for weather data, or perhaps a firewall clash? I have Vista on my laptop and its levels of security are somewhat paranoid by default; I've found it can cause problems of that nature, although admittedly not with FSX in my experience.Al

A lot of it depends on what version of FSX you are running. SP1 and SP2 run a little differently on Vista. You also need to defrag after installing FSX and Vista. The files are scattered all over your harddrive. If you have the 32 bit version of Vista, you need to enable the "3GB switch". If you have the original version of FSX installed or SP1, you also need to edit FSX.exe to show that FSX can "see" more memory than 2GB. If you have SP2 installed, then the FSX.exe was changed by Microsoft to reflect this change and you only need to enable the 3GB switch. If you need info on how to enable the 3GB switch in Vista, do a forum search for 3GB or OOM (OutofMemory). Make sure your video/sound card drivers are up to date. A bad sound card driver or installation will cause a lock up. If you haven't done so, I would run FSX with the default configuration. Just go into settings and save your current settings by giving it a name. Then go to the various config settings and reset to default. See if this works. If so, it's more than likely you have a scenery slider set too high. I doubt your problem is caused by security settings but it's worthwhile to take a look. Hope this helps. Best regards,Jim
