OK, here's a quick example.
On the links to Page 2 and Page 3, which have links to additional sub menus, the MouseOver button goes on the actual menu layer instead of the MouseOver layer. The MouseOff version links via web animation to the Menu Layer and the button that appears on the Menu Layer links to the page.
As I said this is very convoluted and in my case, brain numbing. But it can work and the advantage is you can control the design of the individual buttons as well as the fly out menu buttons.
