If anyone out there can tell me why the right sidebar is pushing the main blog content down the screen, please let me know. The CSS file I'm using should be visible if you want to take a look at it. I've tried everything I can think of, but it's not acting right in Internet Explorer (surprise!). Naturally it renders and displays fine in Firefox -- which should be reason enough for you to switch.
And no, I'm not going to put everything in a giant table. Unless I have to. Sigh.
If it isn't working tomorrow, I will take a peek, but it's time for dinner right now!
Without looking into your source code or CSS yet, I can say that it looks like the main portion of your blog, the center section where your posts are displayed, is being shifted to start displaying immediately below the "Powered by Movable Type" line located in the right-hand sidebar of each page. I had a similar problem with my blog, and it involved removing all "padding" values from the CSS and using only "margin" values. The problem is in the different way that IE renders the box model.
Here are some links you may find helpful in discussing the CSS box model.
