--- Comment #24 from Ladislav Petruš ladislav.petrus@rt.sk 2007-10-15 15:59:24 --- I wanted to confirm previous comment, but I found out that HL2 and all other Source games that are available to me (ep1, ep2, portal) start again normally after upgrading back to wine 0.9.46 even without disabling the in-game community integration.
It may be related to a recent upgrade of the steam client & source engine caused by Valve Orange Box release. Can others confirm that source games start again normally with wine 0.9.46?
