I'm hoping this will be easy for someone to spot.

1. Go to http://www.MJMMagic.com in Internet Explorer. Just underneath our banner, there is a huge white space.

2. Now go to the same page in FireFox. That white space is not there (or rather, very small).

I don't want that white space there, and I can't figure out why IE displays it prominently, and FireFox does not. Any ideas how to eliminate it? I assume it has something to do with either a header.php or a stylesheet.css setting but don't know what to change.

Thanks in advance for any advice you can throw out there.
