Problem when movie starts, it freezes browser

This is a weird problem I’ve NEVER encountered before.

if you visit either of the links ( same site different hosting ) on the initial loadup it actually FREEZES my browsers ( cant click quick buttons ect… ) until the home.swf fades in. When you go back via button / click other links it doesnt do this only on the initial load.

any ideas?
