Bug #: 31298
           Summary: Window managers can't switch between open Excel files
           Product: Wine
           Version: 1.5.9
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

I'm using the setting "allow the window manager to control the windows".

1. When more than one file is open in Excel 2007, they are each shown in my
tray (lxpanelx) and my window manager's task switcher (I've tried with metacity
and openbox).  Activating these entries only raises a tiny little window with
nothing in it, not the actual Excel window with the file.  There is also an
additional entry, and activating it does raise Excel, but it does not allow me
to switch between the different Excel files.  The only way to switch between
the different Excel files is using "View-Window-Switch Windows".

I'm guessing this is related to these messages which Metacity outputs when the
second Excel file is opened:
Window manager warning: Log level 8: meta_display_register_x_window: assertion
`g_hash_table_lookup (display->window_ids, xwindowp) == NULL' failed
Window manager warning: Log level 8: meta_display_register_x_window: assertion
`g_hash_table_lookup (display->window_ids, xwindowp) == NULL' failed

2. Word and Excel behave differently with multiple open files on Windows, so
naturally they also have different problems with Wine.  When more than one file
is open in Word 2007, they are each shown in my tray and my window manager's
task switcher, and activating these entries raises the correct Word window with
the document.  But using "View-Window-Switch Windows" does not work in Word
(N.B. I can't actually test this on the latest Wine, as with it Word always
crashes on startup :( )
