Using Google to Search (on IE8) and post format is off

Site is The Editor’s Blog.

When I search for my blog posts on Google while using IE8 and click on the link, the blog layout is messed up—only the left sidebar is in the correct place. The other content is far down the page. A refresh of the page does correct the layout, but I’m not sure what’s causing the problem.

The site is almost a year old, never had this problem before today.
No problem in IE7, Chrome, or Firefox.
No problem if I use Bing or Yahoo to search rather than using Google.
No problems as of yesterday and I have made no changes—no updates, no new posts, no new plugins.

There is no problem if I type or copy in the URL. The only problem is when I click the link after Google finds the post I’m searching for.

Anyone have any ideas where I should look for an answer?

Thanks.
