Alright I made a post a while ago trying to figure this out and I think I did a pretty good job. It works on a PC in IE6 and NN7, but I'm not sure about other browsers or on a MAC. I'm going to check it out on a MAC in the school's computer lab, but if anyone else can tell me if I need some type of browser detection or XY offset I would appreciate it.

It's not live and at a temporary domain until I am sure this popup stuff works.
