My b2evolution Version: Not Entered

Version:b2evo 3.3.3
Skin: modified evocamp

Every time I go to my home page (or click on the Home link), the background flashes and goes white. The evoToolbar also changes slightly. This doesn't happen when clicking on any other link on the page.

I've modifed the evocamp skin, but I've also setup a test blog using the same skin and can't get it to duplicate the problem I'm seeing. I've removed all the widgets and added them back one at a time, but can't seem to track it down.

I'm thinking it has to be something in one of the posts on the main page that's the culprit, but don't want to fuss with the live blog too much.

Check it out [url=http://www.bushleaguecritic.com]here[/url] if you have time, and see if someone can't point me in the right direction.

Thanks

EDIT: The arrows for the drop-down menus on the evoToolbar are disappearing and coming back. That's what makes its appearance change momentarily.
