How do I make Vertical Spry Menu appear in IE

Question

The URL in question is:
http://www.ambppct.org/index_menu.php
I have inserted a Vertcal Spry Menu on this page. It functions perfectly in Safari, Firefox and IE 8. However it does not appear in previous versions of IE.
Below is the css file:

/* Submenus should appear slightly overlapping to the right (95%) and up (-5%) with a higher z-index, but they are initially off the left side of the screen (-1000em) */

/* Menu items that have mouse over or focus have a blue background and white text */
ul.MenuBarVertical a:hover, ul.MenuBarVertical a:focus

/* Menu items that are open with submenus have the class designation MenuBarItemSubmenuHover and are set to use a "hover" background image positioned on the far left (95%) and centered vertically (50%) */

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.MenuBarVertical 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.MenuBarVertical li.MenuBarItemIE
display: inline;
f\loat: none;

Answer 1

You will have to update your spry code (do not know how (possibly in editing the css), but it is causing the problem).
If you have CS3 or 4, you can use the spry updater extension from -
http://labs.adobe.com/technologies/spry/
Delete your old spry files then apply the spry updater by selecting,  Site - Spry Updater - then select the options req'd.
Check your page works, modify the spry css as required, checking the site in the browsers after every change.
