We are currently using a Tree Type Menu that can load 2 different pages into 2 different frames. It also uses a display at the bottom of the navigation to display either text or a picture as you rollover different menu items (they call it a TV). You can see our current Menu System at www.home2000.com
to better understand what I am trying to explain.
My problem with this menu system is that it uses Java to run the menu. In some cases when it loads it will tell the user they don't have Java installed and then they have to "do the dance" to install Sun's Java on their computer. With Flash we won't have to deal with this.
Even anyone can help or has any suggestions I would greatly appreciate it!
