Yeah ... I was noticing some weirdness there too. I think I've cleaned up the load oddity a bit. All the jQuery should be in the head now ... and I am not sure where the YUI is coming from ... must be part of the template.
And yes some of these links don't work very well, I'm still building out the full functionality. If you keep to the EMDEX II part of the menu it should be mostly functional, w/o the weird load oddity.
