>Do you get the same (or similar) error in other browsers? Did you try to examine this page with developer tools?

Yes, I have the full Firefox Web Development tool opened. I am trying to isolate it to the lowest common denominator as possible. I put in remarks a lot of things. I have a page which is called every 60 seconds. It is a slave so to detect for new mail, for example. And, while trying to find another bug in IE, when I switched to Firefox, I had the same and I am starting to wonder if this could be related. In IE, there is no javascript error. In Firefox, I have this thing which I have never seen before and where a bunch of developers are reporting problems about on the browser's Web site.
