IE CSS Problem

I have code for a menu with a drop down javascript submenu.

It works perfectly in Chrome and Firefox, but in IE7, the CSS makes the drop down list appear underneath the element to the right of the top menu element. I can't figure out why!

Any help would be appreciated!
CSS:
/* Menu */
 
#menu {
	width: 950px;
	height: 40px;
	margin: 0 auto;
}
 
#menu ul {
	margin: 0;
	padding: 0 0 0 25px;
	list-style: none;
	line-height: normal;
	text-align: center;
}
 
#menu li {
	float: left;
}
 
#menu a {
	float: left;
	padding: 10px 20px;
	margin-right: 2px;
	background: #64E11B;
	text-transform: uppercase;
	text-decoration: none;
	font: bold 10px Arial, Helvetica, sans-serif;
	color: #000000;
}
 
#menu a:hover, #menu .current_page_item a {
	background: #3333CC;
	color: #FFFFFF;
}
 
#menu a:hover {
	text-decoration: underline;
}
 
#menu ul div {
	position: absolute;
	visibility: hidden;
	margin-top: 32px;
	padding: 0;
}
 
#menu ul div a {
	float: none;
	position: relative;
	display: block;
	margin-top: 1px;
	padding: 5px 10px;
	width: auto;
	white-space: nowrap;
	text-align: left;
	text-decoration: none;
	background: #64E11B;
	color: #000000;
	font: bold 10px Arial, Helvetica, sans-serif;
}
 
#menu ul div a:hover {
	background: #3333CC;
	color: #FFFFFF;
}
 
 
 
 
 
HTML:

Can you post the HTML? If you haven't validated your code or provided a dtd it can cause compatibility issues between browsers.

The HTML is posted, underneath the CSS.

Both CSS and HTML validate correctly.

I made the changes below. I tested in Firefox, IE8 (in both standards and compatibility mode). I can't test in IE6 or 7 until Tuesday morning.
#menu li
{
    float: left;
    position: relative; /* I added this */
}
 
#menu ul div
{
    position: absolute;
    visibility: hidden;
    margin-top: 32px;
    padding: 0;
    left: 0; /* I added this */
}
 
#menu ul div a
{
    float: none;
    position: relative;
    display: block;
    /* margin-top: 1px;  I removed this for IE; the margin causes the mouseout event to fire when it shouldn't */
    border-top: 1px solid white; /* This does the same as the margin visually and keeps IE from firing mouseout prematurely */
    padding: 5px 10px;
    width: auto;
    white-space: nowrap;
    text-align: left;
    text-decoration: none;
    background: #64E11B;
    color: #000000;
    font: bold 10px Arial, Helvetica, sans-serif;
}
