Hover Menu Issue: IE 7 moves items to the right (CSS)

Hey everybody,

I am a student and while creating a website for my economics club, I encountered a problem that is beyond my head. I usually create the CSS part by somewhat trial-and-error and now Internet Explorer 7 is my only last problem.

I know there have been similar issues before on here, but I'd really appreciate if someone could tell me where my mistake is.

I based my hover menu on this example: http://www.xs4all.nl/~peterned/examples/cssmenu.html

Internet Explorer 7 displays the pop-up menus a couple of pixels to far to the right, hence they are not clickable when you move the mouse to the right. I am also aware that IE6 doesn't display everthing correctly but as long as it works I don't care.

If anyone could tell me what to change in order to make it work in IE7 (without braking the functionality in Firefox, Safari, IE6...), I would be very glad.
Because this is really important to me, I am also willing to give away a lot of points.

In the Code Section, there are two parts: one is the HTML-Website-code, the other part is the contend of a file called "csshover.htc" in order to make things happen on IE6.

Please excuse my English, I am German.
HTML/CSS Source Code (only necessary parts):
 
<html>
<head>
	<style type="text/css">
 
	body {
		behavior:url("../htc/csshover.htc");}
	
		div#PageBox {
			padding: 20px 0px 0px 30px;
			width:auto;
			margin:12px;}
 
		ul#MenuLeft {
			border: 1px solid black;
			width: 105px;
			margin:0;
			padding:0 0 0 2px;}
 
		ul#MenuLeft li {
			display:block;
			font-size:14px;
			list-style: none;
			padding:0;
			margin: 0;}
 
		#MenuLeft li{
			position:relative;
			z-index:9;}
 
		li.MenuLeftFlip ul {
			width:140px;
			background-color:#ffffff;
			padding: 2px;
			border: 1px solid black;
			position:absolute;
			left:60px; /* might be related to IE6*/
			top:0px;}
 
		li.MenuLeftFlip>ul {
			left:105px;} /* might be related to IE7 */
 
		li.MenuLeftFlip:hover {
			z-index:10;}		
 
		ul#MenuLeft ul { 
			display:none;}
 
		#MenuLeft li:hover ul ul { 
			display:none;}	
 
		#MenuLeft li:hover ul { 
			display:block;}	
 
		#MenuLeft li:hover li:hover ul { 
			display:block;}	
 
		ul#MenuLeft a {
			padding:3px; 
			display:block;
			text-decoration: none;}
 
		ul#MenuLeft a:link {
			text-decoration: none;}
 
		ul#MenuLeft a:visited {
			text-decoration: none;}			
 
		ul#MenuLeft a:hover {
			text-decoration:none;
			background-color: red;}			
 
		ul#MenuLeft a:active {
			text-decoration: none;
			background-color:#F8C400;}
	
	</style>
</head>
 
<body>
 
<div id="PageBox">
 
<ul id="MenuLeft">
    <li><a href="#">Item A</a></li>
    <li class="MenuLeftFlip">
    <a href="#">Item B</a>

        <li><a href="#">Subitem E</a></li>
        </ul>
    </li>
    <li class="MenuLeftFlip">
    <a href="#">Item C</a>
        <ul>
        <li><a href="#">Subitem A</a></li>

        <li><a href="#">Subitem E</a></li>
        </ul>
    </li>
    <li class="MenuLeftFlip">
    <a href="#">Item D</a>
        <ul>
        <li><a href="#">Subitem A</a></li>
        <li><a href="#">Subitem B</a></li>
        <li><a href="#">Subitem C</a></li>
        <li><a href="#">Subitem D</a></li>
        <li><a href="#">Subitem E</a></li>
        </ul>
    </li>
    <li><a href="#">Item E</a></li>
</ul>
