--- Comment #40 from Stefan Dösinger stefandoesinger@gmx.at 2010-09-28 09:43:12 CDT --- Valve fixed this issue on their side. It was their fault(GetMessageW forwarded to GetMessageA), although a wine implementation detail(GetMessageA calls GetMessageW) triggered the bug. Valve's bug could have caused issues on Windows too, in theory.
Please make sure your Steam client is up to date if you're still experiencing this issue.
