When I view a detail page about a species, everything in the left-hand column ("General", "Range and Habitat", etc.) is shifted down, leaving a big empty space. The empty space extends to the bottom of the contents in the right-hand column. I think this started when the list of codes was added at the top, but I'm not 100% sure.
The same prolem occurs in Opera 7.54, but not in Netscape 7.2 or Internet Explorer 6.0.
