They do for me. What happens when you try, or did you fix it?
Also, the cascading menu was probably a fun excercize. But unless you want to add about 10 times as many items, you DO realize that it would be much better to have the menu fully expanded?
Oh, and the banner seems nice. Too bad your frame system doesn't let us see all of it (well, without opening in a new window). Scrolling="no" is really very silly. It doesn't do anything unless there is actually a need to scroll.
