Summary: WindowFromPoint Returns Wrong Window
           Product: Wine
           Version: 20040121
          Platform: PC
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-user
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

WindowFromPoint knows nothing about the Z-order of the windows in Wine and so
frequently returns the a background window rather than the foreground window.
This manifests itself as toolbar focus issues in Microsoft Office 2000 while
having an email window open on top of the main window and incorrect window
selection in the Spy++ utility.
Wine also has no concept of desktops and so cannot distinguish the window
coordinates of a window on one desktop to a window in the same position on
another desktop. Again this causes the same issues as above.
As X11DRV appears to not export any Z-order info it seems like this can only be
fixed by The Great Window Management Rewrite(TM).
