--- Comment #2 from Rosanne DiMesio dimesio@earthlink.net 2012-03-18 17:28:46 CDT --- It doesn't crash on my system in 1.5.0. After clicking LAN game, it autoupdates, then then the LAN game window opens and appears to function (clicking things seemed to work). I used winetricks vcrun2008, but nothing else, and did it multiple times with no problems.
This is on openSUSE 11.4 x86_64, Nvidia 8400GS, 270.41.06 driver. Maybe another Ubuntu 12.04 bug?
