Sidebar Problem in IE

Hello,
I’m working on a customized version of the ‘WordPress Default 1.6″ theme.
Everything is looking good in Firefox and Safari, but in IE, the sidebar isn’t floating to the right properly.

CSS: http://believerscenter.com/wp/makehispraiseglorious/wp-content/themes/default/style.css

If I uncomment “float: right;” in the sidebar style, then it gets real weird.

Please take a look, and let me know if there’s any more info I can give that would be helpful.

Thanks so much,
– David
