Horizontal menu bar displays grey in IE - Please Help

Question

These are my first websites and i have created it in DW CS4. Everything is working and i have checked in multiply browsers. The one issue i can't work out is that when viewed in IE the horizontal menu bar looks grayed out. The main menu should be transparent with a white border, while submenus have a .gif image gradient background also with a white border.
Please help, I would be very grateful and if you would ever find yourself in the Maldives i'm sure we could repay the favour.....

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
