Thanks Peter!  Sorry, I forgot to specify - I need this functionality to
work in IE 5.0+, NS 4.7 (if possible) but definitely NS 6 & 7.  I will test
what you have suggested and see how it goes.  The JS example I posted in my
previous email worked in IE 5 - 6, and NS 6 & 7, but no 4.7.  NS 4.7 is not
a huge issue in this case, BUT it would be nice to be able to support it.
