A: 

Have you tried the iframe trick (i.e. floating an iframe behind the menu, thus putting hte flash layers behind.)

Try setting wmode to transparent - see here

A: 

The iframe-trick is only for IE (below IE7), so it probably would never help in Firefox.

I'd try to enable wmode=transparent, so that the Flash content won't get its own HWND

A: 

Enabling wmode=transparent is the way to go. But also note, that Firefox in Linux does not obey that, and the flash will always be on top.

Can anyone tell me how to float an iframe behind the menu to put the flash layers behind? We have the reverse problem (that menu won't show on top of flash in Explorer, but works in FF and Safari).

hi, wmode=opaque seemed to work for me

I did it here:www.toolgal.com, hover over the products menu on the top navigation

A: 

Use z-index and set the menu to something like 100 and the flash movie to something in the negative like.....say -1.
