269) Why doesn't MWM display an iconify button on my dialog windows?

Answer: MWM (and some other window managers) does not allow transient windows
to be iconified.  Transients are automatically unmapped when the main shell is
iconified and they are re-mapped when the main shell is restored.  If you do
not want this transient behavior, you should use top a TopLevelShell widget
instead of a XmDialogShell widget for your windows.
