Right, I was using "over" and "contained by" interchangabley. I didn't
mean "over" in the context of, say, z-orders.

Well, you did help me with that, but at the time I did have some
alternatives. But all those alternatives required working with scripts
in Code view. The menu system at
http://www.interlacken.com/dhtmlmenu/dhtmlmenu4.htm
for example, doesn't use any transparent gif layers, doesn't use any
graphics for the rollovers, and works fine no matter where the menu
ends up on the page.
The code in that page isn't as trim as it could be, but it's bloated
enough that if I used the same techniques in a real site, I wouldn't
want to maintain it. That's why I kind of lost interest.
ASP.NET Menu from ComponentArt seems like a nice product, and my host
provides the run-time on their servers at no additional charge. But
it's really meant for .NET developers, and I haven't wanted DHTML
menus badly enough to cough up $250 for the developer license.
