All About the Sidebar, Baby

Is anyone else who uses Blogger having trouble with their sidebars? Mine will appear as the page is loading, but as soon as the page is done loading, it disappears. I don't know of any HTML issues that would cause this problem, but I could be wrong.

Anybody?

UPDATE: Okay, I found the issue. This tool can't be bothered to use actual spaces, and instead resorts to using periods. Someone looked at her blog, decided that it wasn't worth continuing to look at, and hit the "next blog" button, which brought them here. Since the entire "sentence" registers as one long word, the word wrapping is hosed up, and it forces my sidebar to the bottom of the page.

Wanker. Should clear up in about twenty-two hours.
