This seems quite different than the issue I had with an ActionListener
responding twice (it was added twice).  I've even checked to make sure this
list box has only one ListSelectionListener.

I have a JList that allows multiple interval selection and the
ListSelectionListener is called when I press the mouse button down and when
I release it.  Somewhere along the way, I also get a third event.  I added
a line to the start of the valueChanged() method and it prints once when I
press down on the left mouse button and twice more when I let the button
up.

I can't find anything in the ListSelectionEvent that lets me check to see if
the event is from a mouse button down or up or a mouse click and I haven't
found a reference to this happening.  I haven't had this problem before, so
I could see how it's related to allowing multiple intervals, but I'm still
not clear on what is going on.

Why am I getting multiple ListSelectionEvents and what do I do if all I want
is one so I can then get the selected indices from the list?

Thanks!

Hal
