Summary: PowerPoint 2007 doesn't show two or more instances
                    correctly in the task bar
           Product: Wine
           Version: 1.3.5
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Since wine version 1.1.42 I observed that when two or more instances of
PowerPoint 2007 are opened, only the first is accessible through the task bar.
One can navigate through the various instances alternating the windows shown
inside PowerPoint but not clicking on the tabs showing Presentation1,
Presentation2, ... in the task bar as this action does nothing. Despite this
strange behaviour the various presentations can be run or created without
problem, the user having to choose the windows from the program menu.
