I am not seeing it. I've got IE9 and Firefox 4 here.
However, it would appear in either browser that the hover class on the rollover menu in the Welcome to shmax.com box (ui-state-active) has a slight overhang on the top border that does not appear on the inactive one. Is this on purpose?
Also the span.separator (sic) that has the headings for things like "Photo of the Day" and "More news" could use some padding on the left since in both browsers the first letter "P" or "M" clips the edge of the gray picture used as a background for those divs.
