Steps to reproduce the problem:
Install LFS S2 W (full install)
Install patch W9
Open LFS
Press Alt+F4 to exit the game while the replay is playing.
The machine will hang at a light blue screen. Your only option is to end task on LFS. It looks like the game is expecting to go to the first time setup where you pick your driver, mph/kph, etc., and that it can't handle doing the Alt+F4 exit at that time. Hitting ESC, then clicking exit works fine. I haven't tested this without patch W9, but I'm sure that a clean install of W will reproduce the bug as well.
