LFS keeps freezing my whole computer (mouse and other programs included) in single player, not sure why. It freezes for about 10 seconds then unfreezes, then refreezes and repeats if I stay on the track. I tried getting latest video driver off NVIDIA's site, hasn't helped. I have Windows XP SP3 and LFS Y24 but have noticed it in Y22 too. I tried fresh installing LFS (then patching to Y24) and it happens in that too. It hasn't happened in multiplayer, only singleplayer. Doesn't happen during the menus but happens only while I'm on the track. I'm still trying it while I type this and it seems only certain cars do it. LX4, LX6, RB4, so far do it while XFG and MRT don't do it.
