Great! Thanks.

Okay, I will continue down that path then :)

My plan currently is to get it working first, and then make it pretty :)

This was in Internet Explorer, with the most recent java JRE off of
java.sun.com.

That might work. I'll look into the View.pm file and see how things are
happening there. I still think you will end up running into a problem when
you have one network/subnet/address that you need/want to be in 2 different
views at the same time.
