Summary: menus disappear from menubar in MDI app
           Product: Wine
           Version: 0.9.29.
          Platform: PC
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-binary
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When I upgraded from 0.9.22 to 0.9.29, I noticed that entire menus disappeared,
starting at the left, from the menu bar.

I am using a home-grown MDI app.  The only related event that I can think of is
MoveWindow(), which is use to resize a new MDI child, depending on which window
I open.

In some cases, the app starts up and the File menu is missing from the get-go,
without opening any MDI child windows.

In the Wine debug mode, I can see "RemoveMenu" when a menu is eliminated.  My
program does not call RemoveMenu at any time, although it does switch back and
forth between two menus -- one menu is for when there are no MDI child windows
open, the other is displayed with children open.

When I re-installed 0.9.22, the problem went away.
