I ran across a strange issue with some flash based navigation in firefox. In the flash movie I have a banner with the navigation links under it. The main content area is a CSS 2 column layout. everything works wonderfully in IE6 however the flash rollover buttons do not work in Firefox.
I am using the Flash Detection Kit to embed the flash correctly and I am setting the WMODE to transparent in the code. The div I am using to hold the flash element is relatively positioned and the main content holder has a set z-index of 1. Any of these things might be causing the problem but I have yet to be able to fix it.
