Template layout on my embedded gallery page

Hello,
I'm hoping someone may be able to help me figure this out. My site is www.haikuherps.com and the embedded gallery is at http://www.haikuherps.com/index.php/component/option,com_gallery2/Itemid,41/

With Internet Explorer, when browsing my embedded Gallery page, the right-side Joomla panel holding my Main Menu shows up lower down in the page than it should. All other pages in the site show up properly, and this problem does not happen with Firefox.

I'm using Joomla! 1.0.13 Stable , Gallery 2 Bridge 2.0.14 Beta, and Gallery 2.2.2 core 1.2.0.4

Any advice would be appreciated, as I have been unable to fix it myself.
