WTH is this "loading essential modules" popup???????????

I'm using the Firefox browser, it doesn't allow popups unless I tell it, and corearts is not on my whitelist. I'm not happy with the long delay to load up each flash anim, either. And why abandon the original window?

ARGH!!!! My eyes! I just hovered the pointer over a thumbnail!

Who designed this... thing? Is anyone copying this thread to them?
