extremely simple borland C builder app hangs
Hi! This is still the same app, that used previously for testing freereport. How the app works. 0. show main window 1. call simple and meaningless freereport funtions (works now) 2. show [OK] dialog saying what above function returned 3. allow to press [OK] (of course ;-) 4. show main windows until it's closed. The app hangs after or around [2] it seems. Frames of main window and of the dialog show up, hovever their content is not painted and I cannot click/Enter/Esc/space anything. Final part of +relay log is this: 08072028:Ret x11drv.SetWindowPos() retval=00000001 ret=408c83ef 08072028:Ret x11drv.ShowWindow() retval=00000001 ret=408c7690 08072028:Call x11drv.MsgWaitForMultipleObjectsEx(00000000,00000000,00000000,00000000,00000000) ret=408deb6f 08072028:Ret x11drv.MsgWaitForMultipleObjectsEx() retval=00000102 ret=408deb6f 08072028:Call window proc 0x418a0fef (hwnd=00010021,msg=WM_USER+ac00,wp=00000000,lp=00000000) 08072028:Ret window proc 0x418a0fef (hwnd=00010021,msg=WM_USER+ac00,wp=00000000,lp=00000000) retval=00000000 08072028:Call x11drv.MsgWaitForMultipleObjectsEx(00000000,00000000,00000000,00000000,00000000) ret=408deb6f 08072028:Ret x11drv.MsgWaitForMultipleObjectsEx() retval=00000102 ret=408deb6f 08072028:Call window proc 0x418a0fef (hwnd=00010021,msg=WM_ENTERIDLE,wp=00000000,lp=0001002a) 08072028:Call user32.DefWindowProcA(00010021,00000121,00000000,0001002a) ret=40620e03 08072028:Ret user32.DefWindowProcA() retval=00000000 ret=40620e03 08072028:Ret window proc 0x418a0fef (hwnd=00010021,msg=WM_ENTERIDLE,wp=00000000,lp=0001002a) retval=00000000 08072028:Call x11drv.MsgWaitForMultipleObjectsEx(00000000,00000000,00000000,00000000,00000000) ret=408deb6f 08072028:Ret x11drv.MsgWaitForMultipleObjectsEx() retval=00000102 ret=408deb6f 08072028:Call x11drv.MsgWaitForMultipleObjectsEx(00000001,403c53e8,ffffffff,00000000,00000000) ret=408dee6d So it seems that MsgWaitForMultipleObjectsEx doesn't return if it has anything to do (first parameter is number of objects to wait for). It is almost exactly the same, as the "big app", which hangs at this: 08072028:Ret window proc 0x422408ed (hwnd=0001004d,msg=WM_PAINT,wp=00000000,lp=00000000) retval=0000000008072028:Call x11drv.MsgWaitForMultipleObjectsEx(00000000,00000000,00000000,00000000,00000000) ret=408deb6f 08072028:Ret x11drv.MsgWaitForMultipleObjectsEx() retval=00000102 ret=408deb6f 08072028:Call window proc 0x42240fef (hwnd=00010021,msg=WM_ENTERIDLE,wp=00000000,lp=00010052) 08072028:Call user32.DefWindowProcA(00010021,00000121,00000000,00010052) ret=40620e03 08072028:Ret user32.DefWindowProcA() retval=00000000 ret=40620e03 08072028:Ret window proc 0x42240fef (hwnd=00010021,msg=WM_ENTERIDLE,wp=00000000,lp=00010052) retval=00000000 08072028:Call x11drv.MsgWaitForMultipleObjectsEx(00000000,00000000,00000000,00000000,00000000) ret=408deb6f 08072028:Ret x11drv.MsgWaitForMultipleObjectsEx() retval=00000102 ret=408deb6f 08072028:Call x11drv.MsgWaitForMultipleObjectsEx(00000001,403c7eb8,ffffffff,00000000,00000000) ret=408dee6d It seems, that dll/x11drv/event.c:X11DRV_MsgWaitForMultipleObjectsEx is being called which in turn is calling scheduler/synchro.c:WaitForMultipleObjectsEx (I think). I looked at the code, but ATM it's still black magic for me - too many unknown wine interlans ivolved :-/ Is this known problem? What should I look for while debugging? Any pointers/hints? (I don't mean general wine-developers docs pointers) Regards Grzegorz B. Prokopski PS: I compiled wine from CVS, but not today's version (as it had some problems with compilation) but 2 weeks old.

I'm currently researching the problem with the same symptoms - cygwin installer hangs on the call to x11drv.MsgWaitForMultipleObjectsEx. Plus, very recently I saw similiar hang signature in some other bug report in Bugzilla. I have source of the installer and am trying to localize the issue.

Grzegorz, I found the cause of my problem, I wonder if you have the same issue. In my case was the problem was caused by not implemented processing of property sheet message PSM_SETCURSELID. The application printed to terminal a fixme message: fixme:propsheet:PROPSHEET_DialogProc Unimplemented msg PSM_SETCURSELID Do you have the same message in the application output?

Do you have the same message in the application output? No, I don't. My full output when I 'just' run wine and my app is this:

It's not impossible that this is the reason for such behaviour of MsgWaitForMultipleObjectsEx - a side effect of earlier problem. I'll take a look at TPreviewForm::FormResize - maybe I'll learn sth. Thanks for all Grzegorz B. Prokopski PS: I _am_ subscribed to the list, no _need_ to Cc: me (but you may if you wish, such mail is sorted to Wine's folder anyway - no diff for me)

This shouldn't be a problem at all because FlatScrollBar controll defaults to the ScrollBar controll if the FlatScrollBar wasn't initialized. This behaviour is documented by msdn.
