           Summary: Top level window loses focus when selecting a menu
                    item
           Product: Wine
           Version: 1.1.21
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2

Hi,

For a couple of days I have been trying to locate a bug in a program I'm
working. The program itself is written in Smalltalk using Visualworks. Under
the hood Visualworks is doing all win32 gui drawing itself (it also works on
other platforms).

The program in question has a top level window on which a win32 interface is
drawn including a menu bar. Clicking on the menu bar inactivates the top level
window. I have been debugging it for some days and I think it is somehow
related to SetFocus. Disabling all SetFocus / SetForegroundWindow calls in
user32 appears to make the issue disappear. The app itself only calls SetFocus
but Wine itself makes SetForegroundWindow calls.

The menu window has WS_POPUP and WS_DISABLED set (the top level window also has
WS_DISABLED set). Further Alexandre suspects there is something wrong with the
focus handling code in case of WM_MOUSEACTIVATE.

I have uploaded a test app which illustrates the problem to: (note the server
isn't always online) http://roderick.student.utwente.nl/menutest.tar.gz
I have also attached a log of +win,+msg to here. The app window is called
'vwnt'.

Regards,
Roderick
