stuck drop down

[colonel5]

In IE7 my drop down menu periodically gets stuck, meaning it will appear and then won't go away no matter where you roll your mouse. I can't figure out if it's the css or the javascript.

The menu is the purple bar with the different logos on it (HP, Xerox, etc)

Any ideas would be appreciated

Here's the javascript


<script type="text/javascript">
// <![CDATA[

sfHover = function() {
var sfEls = document.getElementById("nav").getElementsByTagName("LI");
for (var i=0; i<sfEls.length; i++) {
sfEls[i].onmouseover=function() {
this.className+=" sfhover";
}
sfEls[i].onmouseout=function() {
this.className=this.className.replace(new RegExp(" sfhover\\b"), "");
}
}
}

if (window.attachEvent) {
window.attachEvent("onload", sfHover);
}

// ]]>
</script>
<SCRIPT LANGUAGE='JavaScript'>
function openListBuilder(url)
{
popupWin = window.open(url, 'openWin', "width=400, height=250, scrollbars=yes, resizable=yes");
}
</SCRIPT>


Here's the css
