Summary: overlapping screen MDI (shows only background)
           Product: Wine
           Version: 0.9.36.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: test
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

This program I'm using is shown as MDI. Normally multiple windows are detached.
If I press F5 they all appear at once nicely layed out with the grey background.
This  happens in Windows. However under Wine only grey background appears (as if
it was overlapping the proper windows. In the attachments there's a screen with
correct behaviour, the one with Wine (incorrect) and log file

This didn't happen in the older versions (Unfortunately I don't know in which
version it appeared)
