Please take a look at the above link.
In Opera and IE the 2 logos at the bottom appear below the list of links. In Mozilla, Firefox and Netscape they over lap the last link line
Also in IE the lits of links at the ned of the page is spaced widely
In Opera, Mozill, Firefox and Netscape) the list is spaced more closely (probably correctly) - this is not a major issue but is possibly related to above.
