I not too sure if this is fixable or not but heck if it is and you know how hit me up a pm with your MSN ID and I'll add you. I got a blog with a template that don't exactly work properly with the Explorer browser but it's fine with FireFox. Cheers
Its not a unique problem with your blog but most of the modern blogs gets "screwy" with internet explorer. However you can make changes so that they are properly displayed in IE but it wud req more CSS modifications and javascripts changes. That would definitely blow up ur site SEO ! I can make changes if you like but my honest advice is let it unchanged.
