Height Issue

I haven't checked into the javascript yet but there seems to be a height issue with the theme. If you check out:

http://www.cityethics.org/content/full-text-model-ethics-code#TOC68

You will see the theme is truncating the page at this height. I have tested this page (and ran the code through a cleaner to make sure the HTML inside of the page node was not to blame) on a couple of different themes and the 960 Robots is the only theme cutting this page in half. I also created a couple of other nodes to make sure this node wasn't corrupt or anything and I get the same issue on those additional nodes as well.

Any help as to the cause of this would be not just awesome - but hawsome!
