Summary: wine window disappears on certain window managers
           Product: Wine
           Version: CVS
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Environment:
  Wine 20050419
  Linux Mandrake 10.1
  Wine built from Mandrake Cooker RPM on Mandrake 10.1
  AfterStep 2.1.0 window manager
  Managed = Y
  Application Running Under Wine: Lotus Notes 6.5.2

After upgrading from wine 200402xx to 20050419 I found that when switching
virtual desktops the wine x11 window would disappear and appear to be lost by
AfterStep (it drops out of the window list).   Messages continue to appear in
the debug log that shows the wine app to still be running (a scheduled agent is
kicking off every 10 minutes which causes wine messages).

This same thing happens with the FVWM2 window manager as well.

When using KDE3.2 on the same machine changing virtual desktops doesn't make the
window disappear, though changing with key shortcuts has the very odd behavior
of the wine window stealing focus and changing the virtual desktop back to the
one wine is on.

Again, with Wine 200402 everything worked as expected.

Any hints on possible work arounds or debug flags I can turn on to help narrow
this would be appreciated.
