CSS bug in windows

Hi guys and gals,

I worked on a site www.uscarpetcare.com and there seems to be a bug in the CSS. I am on a MAC and everything works fine. I have tested the site on older windows machines, but the client has VISTA and of course that is the only place where the bug is appearing.

The lower part of the site (address, contact info) is covering the copy. Is there anyway anybody knows what is going on or does anybody no a way to test this other than having a windows VISTA box?

Appreciate any help.
