I found the sim started freezing (resulting in CTRL-ALT-DELETE or reset) after installing the patch.(it had run without problems of this sort before the patch) After fiddling around all afternoon (I downloaded new drivers for everything, did a clean install etc. all with no joy)I went into my BIOS and disabled my onboard LAN and Firewire ports (which I don't use anyway) since doing that it has only crashed once and that was because I enabled cockpit mouse (which incidently resulted in inverted 'fisheye' graphics, anybody got a cure for that? I assume it is a bug created by the patch)

My rig:
AMD Athlon XP 2800+
512MB RAM
GeForce FX 5600
Audigy 2 EX
Saitek X45
