Found it:
In the hack on the CSS sheet - change background from #FFF to
transparent:
BROWSER HACKS: the hacks below should not be changed unless
you are an expert
/* HACK FOR IE: to make sure the sub menus show above form
controls, we underlay each submenu with an iframe */
ul.MenuBarHorizontal iframe
position: absolute;
z-index: 1010;
/* HACK FOR IE: to stabilize appearance of menu items; the
slash in float is to keep IE 5.0 from parsing */
@media screen, projection
ul.MenuBarHorizontal li.MenuBarItemIE
display: inline;
f\loat: left;
background: transparent;
