I'm having a problem with my sidebar in my single post pages. It's pushed all the way to the bottom. Here's an example: http://www.basketballjohn.com/2008/01/03/recap-philadelphia-76ers-utah-jazz-3-january-2008/ . I think one of my widgets is causing it, but I can't find the right one. But if I restore it to the defaults for the theme, it still does it. What file and code should I be looking for?
