[link removed]

In IE6, the category "At-A-Glance Telephone/Address Book" has a large vertical gap inserted at the first space. It only happens on this page (that I've found). It doesn't happen on other pages with the same number of nested lists. Shortening the name of the category so it doesn't wrap just moves the gap to the next category down.

Any idea what's causing this? Thanks much in advance.

That's really odd, but it looks like it's the accumulating padding as you drill down that's the problem. When I changed the padding-left to zero, the big gap went away.

That did the trick, thank you!

Removing the link now.
