I had it everytime when alt+f4'ing in the 3 seconds after the map appeared ;o
Even in singleplayer. But as it it's fixed now...




is that common?? I'm using a laptop with core 2 duo T8100 (2,1ghz) and nvidia gforce 8400M GS... I know that graphic card is no high end gaming device but it was working well with LFS until now...now it's slightly stuttering in some situations 
Anyway, it seems like ABS will make LFS more competitive.
