First let me just say this menu is absolutely fantastic and the responsive support in these forums is unbelievable. I have implemented Milonic on 20 sites so far and it makes navigation development so easy. Kudos to all involved in this fine product.
Anyway, the problem for today is the menu displays under/behind Flash objects in Firefox 3. And even in FF2 with the current release (5.802). Am running Windows XP.

Oops, never mind, just found the answer... Use <script src="http://milonic.com/insert_active_flash.js"></script>
