Question about admin view IE vs FF

Andrew,
or someone having the answer, I just started noticing a problem viewing the blogs list in admin now that I have two pages. It works fine in firefox but in ie it kicks the main content of the page down below the left menu.
here are some screen shots to look at
http://ismyblogs.name/ffss.jpg < firefox, this ones fine
http://ismyblogs.name/IEss.jpg internet explorer, main content kicks down below left menu
http://ismyblogs.name/IEss2.jpg internet explorer, scrolled down so you can see where the content starts.

Thanks for any help.
