[Plugin: Google XML Sitemaps] IE problems

I’ve installed Google Site Map Gen. and it came to my attention from a friend that Internet Explore renders the site map when he trouble shoots my payment process. Google Site Map. generates a site map on the page of my purchase order and pushes all the CSS, moving everything out of place. How in the world does that happen? Better yet, how do I fix the problem?

I work on an Apple and use Firefox and Safari. I don’t have the problem that my friend is having, however, he said that it only happens when using Internet Exploer.
