I'm trying to run notepad on WINE, with DISPLAY environment variable
pointing to Cygwin (X Server 6.7.0.0-12) running on my Windows XP
machine. It works rather OK-ish, but when I try to close Notepad, it
gets stuck in GetMessageW function call after displaying a "text
changed, do you want to save ?" dialog box:
trace:msg:GetMessageW (1117) mask=0000007f, bits=00000000,
changed=00000000, waiting
0009:Call kernel32.ReleaseThunkLock(406ce6f8) ret=409b79a3
0009:Ret kernel32.ReleaseThunkLock() retval=00000000 ret=409b79a3
0009:Call
x11drv.MsgWaitForMultipleObjectsEx(00000001,403893f4,ffffffff,00000000,00000000)
ret=409b79c7
0009:Call
kernel32.WaitForMultipleObjectsEx(00000001,403893f4,00000000,ffffffff,00000000)
ret=40ce1838
0009:Call
ntdll.NtWaitForMultipleObjects(00000001,406ce32c,00000000,00000000,00000000)
ret=404e8989
I guess the bug is not in notepad, but in Wine message handling, as it's
not the only program, that freezes after displaying a dialog box. It
doesn't happen when MessageBox is called from WM_KEYDOWN handler, but it
DOES happen when MessageBox is called from WM_CLOSE handler, but only if
WM_CLOSE was sent by system after clicking Close or presing Alt+F4, and
not sent or posted by application itself.

Any idea what it may be ? deadlock ? The version of Wine I'm using was
grabbed a couple of hours ago from anonymous CVS.
