I have a follow-up item on this, wondering if anyone has a solution:
First of all, the method for refreshing initial content that David
Ethell sent, below, is a great addition.
However - something I've noticed is that when the content rolls back
into place, the stylesheet is not applied. It is one, ugly bulleted
mess. I can't seem to get the style to apply to the UL content once it
rolls back. I can reload the page, but - well - that's even uglier.
Any ideas?
