Created attachment 55750 [details] PUSHAW/POPAW handling This issue also shows when trying to run Mass Effect 2 (demo or full version) through Wine. I'm attaching a patch implementing the missing piece of code: it seems to let the program go on, but I'm not really sure of its correctness.

I don't see this in valgrind-3.9.0 and wine-1.7.19-70-gd6a59f7. Mass Effect 2 doesn't run under valgrind, however. If I run MassEffect2.exe directly, wine fails to load umbra.dll (which is in the cwd). If I run MassEffect2Launcher.exe, the launcher displays and I can click play, but it fails shortly after with the same umbra.dll issue.
