Bug #: 30587
           Summary: Office 2007 apps (Word, Powerpoint) cannot be
                    maximized after being unmaximized by window manager
           Product: Wine
           Version: 1.5.3
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Tested with Wine 1.5.3, Ubuntu 12.04 LTS x64 from Wine PPA Package version
1.5.3-0ubuntu1~ppa1~precise4+pulse17.

To reproduce:
1. Open Word 2007 or Powerpoint 2007
2. Maximize the window using the Word/Powerpoint maximize button in the
upper-right corner.
3. Unmaximize using the same button
4. Maximize the window again using the same button
5. Unmaximize the window using the window manager (e.g. in the unity global
menu use the unmaximize button, or in Gnome's window list, right click and
choose unmaximize)
6. Window cannot be maximized anymore with the maximize button.

Also, doing the same but swapping the office button with the wm button in all
steps results in a window that can't be unmaximized.
