Byron, when you receive an event from Intuition, you have to handle all the
events at your port.  If you get another while or before handling the first,
you won't get another signal.  This means that you'll have an event on your
queue, but won't react until another event happens.  Suddenly you're out
of sync, reacting to a different event than caused a signal!  Just loop
after handling an IntuiMessage back up to the GetMsg till no more are there.
Then you can wait on the port again.
