superfish submenu in IE8 has Gap

superfish submenu in IE8 has Gap

I can't seem to figure out how to fix the gap in the sub submenu without affecting other browsers.  IE8 keeps messing it up but if I change the superfish.css to whats below it messes up all other browsers.  

ul.sf-menu

li li:hover ul,

ul.sf-menu

li li.sfHover ul {

left9.5em/* match ul width */ IF I CHG THIS TO 9.5em messes up other browsers

top0;

}
