CSS positioning problem on entries with no comments

Hi!

On entries that have no comments, my sidebar moves to the bottom of the page.

Please see https://ganai.com/wp/2008/08/post-4-yada-yadadity-yada/ to look at what I’m talking about.

Compare that to https://ganai.com/wp/2008/08/post-2-yada-yadadity-yada/

As soon as there are comments on an entry, the sidebar moves back into the right place.

How can can I make the sidebar stay in the proper place even on entries with no comments?
