I can give you some hints: In IE - using the developer tools - the divs are not being positioned properly beginning with the dialog and content divs around the image and details. When I added position:relative, just to explicitly tell IE how they should be positioned - it seemed to clear up the problem.

I had to add position:relative to these two divs to move them back into place. These are the divs that are the parent divs for your content that is not being positioned properly
.dialog
.content

These divs get used a lot - so you might have to experiment to make sure relative positioning is okay in all browsers - or add more classes to refine your changes specifically to these divs.
