Lots and lots of programs use a single port for multiple windows, using
CloseWindowSafely() and the protocol described in the V1.2 Intuition Enhancer
document.  There is a field in the IntuiMessage to identify the window
to which the message pertains.

If there are problems, let them be known.  If you think the problems might
have been your own or you don't understand what was going on, don't post
to the contrary.  Please be specific or don't bother answering.  The original
poster would now think that ports cannot be shared, when indeed they can and
are for many programs, including the Workbench.
