--- Comment #2 from Bas Koopmans winebugs@badako.nl 2009-12-10 02:49:06 --- I wanted to do a regression test, but I couldn't get Garrysmod to work under any version of wine I have on my PC (For reference, I have the source for every version of wine since 0.9.11 on my PC).
Therefore I'll consider this bug invalid, as the problem most likely lies in my system and not in Wine.
