The first time you open up the site with Firefox, it ignores the preloaders (placed in the main movie) of the external swf and also their containers _visible properties(like if the playhead would just jump 2 frames). If you hit refresh, it does work at it should and you can even see a glimpse of the preloaders.
I work with IE (where it does work fine)and just discovered the problem. Any quick fix???
I did try searching.
