Summary: application splash and incorrect Z-Order
           Product: Wine
           Version: 0.9.40.
          Platform: PC
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-user
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Some applications show their splash during startup and such windows are the 
same as normal windows, except their caption is hidden.
When such application starts under Wine and shows an error box, the error box 
will appear below the splash window. 
The same goes for the window where Wine asks to install Gecko. It happens in 
response to application's attempt to initialize embedded IE browser.
I could replicate the problem with a splash created with Style = 0x86000000 
and ExStyle=0x10000
