Spry Image button not working on IE

Question

Hi,
I have a image button on a spry menu that displays fine in firefox and safari, but not in IE. It is just opaque on the menu buttons to the page background.
It's a personal site for a wedding that i need to go live with in a week or so,I can't figure out what I'm doing wrong so hope someone can help.

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;
    filter:alpha(opacity:0.1);
/* 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: #FFF;

Answer 1

Sorry, but I do not see that you have added the code. Not only that, I think I may have made a boo-boo by saying that the background-image should be modified. The original says
/* 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: #FFF;
so that background should contain the image, not background-image.
