Spry Menu Text only displays in hover color, doesn't sense browser edge

Question

I have a Spry horizontal menu in a website that is working fairly well in everything except IE6.  Firefox, Safari, and IE7 are all fine.
In IE6, random menu items only display in the blue hover color, so they are invisible until you hover over them.
My second problem is that the menu is right-aligned, and the button on the far right has three submenus.  I would like the second two submenus to automatically open to the left of the first submenu when opening to the right would cause them to be cut off by the edge of the browser window.  How do I do this??
Here is my code (I've customized it with suggestions online, but just can't seem to fix the problem with IE6).
Thanks for any help, I'm really stuck!!

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;
@media screen {
* html ul.MenuBarVertical ul {position: relative!important; float: left;
margin: -10px -1000px -1000px 80px; display: inline;}
* html ul.MenuBarVertical {position: static!important; }
