Nice job. I created something extremely similar a few months back for my day job (wow the traffic I missed out on!). One thing I've encountered in this and in my own implementation: the hint gets blocked by iframe if it's nearby. Has anyone figured out a way to reliably have it appear over the iframe instead of under? I've been struggling with it for a while and have not figured it out.
