--- Comment #57 from Fabian Maurer dark.shadow4@web.de --- Well, I thought this would fix the issue, but there seems to be something missing. Do you know how to build the tests? Could you please run "user32_test msg" on your linux machine and post the log? It should cover this issue, and I'm curious to see what the test says.
