cross browser menu hover is underlining in IE8 but not in the rest of the browsers

I need to turn off the hover underline in IE8 -

here is my dev site: http://www.solutionunion.com/website/

on the main menu dropdown when you mouseover in ie8 it underlines the link but not in ff or any of the other browsers. is there a special hack I can add to the css file to make the underline on the hover turn off?

you have this in the containing TD

(the id of the td I looked at was 'dm0m3i0tdT')
