Disappearing horizontal spry menu in IE.

Question

Hi,
I dont usually have any issues with spry menu, but this time the website was going to have lots of pages, and i wanted to be able to update the menu once so I made the menu as a library item. It looks good but in IE it shows bugs.
The whole menu showing up white in IE and only when you roll over it does it show the particular menu selection. Then I found a form on here that told me to change the position to "relative" now I have a new issue where the whole menu including the sub menu's has pushed all the content down and there is a big space and in the browser comparability it shows me its a "z-index bug". I have tried fixing it but it just does not want to work. Can anyone help, please.
Here is the website http://www.thesimplethings.ca
here is the spry menu code:

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 */

    ul.MenuBarHorizontal li.MenuBarItemIE
        display: inline;
        f\loat: left;
        background: #FFF;

I have noticed that you have removed the above. There is still a problem in IE6 in that the background colour remains white.
To solve this, remove the red parts and add the green parts
ul.MenuBarHorizontal {
    margin: 0;
    padding: 0;
    list-style-type: none;
    font-size: 14px;
    cursor: default;
    width: auto;
    font-family: Arial, Helvetica, sans-serif;
    z-index: 10;
    background-color: #424242;
ul.MenuBarHorizontal ul {
    margin: 0;
    padding: 0;
    list-style-type: none;
    font-size: 100%;
    z-index: 1020;
    cursor: default;
    width: 13em;
    position: absolute;
    left: -1000em;
ul.MenuBarHorizontal ul li {
    width: 13em;
    background-color: #424242;
    border-top-width: 1px;
    border-top-style: solid;
    border-top-color: #FFF;
    color: #FFF;
ul.MenuBarHorizontal a {
    display: block;
    cursor: pointer;
    background-color: #424242;
    padding: 0.5em 0.75em;
    color: #FFF;
    text-decoration: none;
ul.MenuBarHorizontal iframe {
    position: absolute;
    z-index: 1010;
   filter:alpha(opacity:0.1);
