Paschal L has blogged a couple of interesting methods for doing rollovers. I'm adding these to my box of tricks.
OK so I grew up learning HTML in the mid to late 90's so I have been using tables to layout pages for a long time now. It's burned into my brain and very difficult to unlearn. But today I read an article that may get me to change my mind. Using CSS2 you can do a lot more than you could with the older stuff. For instance using the border effects in CSS2 you can save yourself a lot of bandwidth by eliminating the graphics we used to suround things with. The same can be said for rollover buttons.
This is very important to me because a lot of my users are on extremely limited bandwidth connections (ie ships at sea). Good Stuff Guys.

The portal enhancments (for lack of a better term) that I'm working on at work are going really well. We're using the drill down report style from the starter kits and filling each drill down with live data from remotely hosted web services. Remarkably the web services seem to work faster than then demo we did using dummy data in SQL 2000. Gotta love DOT NET!
