Firefox Mac Flash DHTML dropdown menu bug

[Chobbix]

1) Script Title: AnyLink Drop Down Menu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...pmenuindex.htm

3) Describe problem: This script is great and works so well in everything other than Firefox on the Mac (works great in firefox PC). As you can see (if you have a Mac) in the link below which I am developing, the Flash does not display unless it is clear of the dropdown menu (I have tested this by absolutely placing the flash div further down the page).

Please please help any Mac users out there as I have tried everything (i think) such as playing with z-index and absolutely/relatively positioning things.

Thank you in advance for your suggestions.
