Ok, I'm not sure about it waiting for that event. The call is
0009:Call kernel32.WaitForSingleObject(00000048,ffffffff) ret=00401c00

Anyway I wrote a test app, showwindow.c.  It is available on . The relay log is there too. The test app tries
to mimic the calls I see.  I tested under wine and it does hang. I
will see about windows.

BTW, I replaced the SendMessage in set_active_window with
SendMessageTimeout where ever thread 0xc would hang sending to 0x9 and
doing that would make it work normally, but I don't know if that is
what you want and I want to see what windows does first.
