Flickering Layer When Using UL and Links...

I have a bit of a strange issue with a CSS styled unordered list
(contained within a <div>).

The layer is acting as a drop down when triggered by a JS onmouse
event of a link - this works fine.
However the layer has a unordered list containing links - when you
hover over the link, the layer flickers quickly. If you move your
mouse away from the UL area, it is fine, which indicated to me that it
is a <a>/<ul> issue.

My code is below... does anyone have any idea why this is so?

TIA

JS Layer Trigger Code
====================

<script language="javascript" type="text/javascript">
function depMenuTog()
{
if(document.getElementById("depmenulayer").style.d isplay=="none")
{
document.getElementById("depmenulayer").style.disp lay="block";
}
else
{
document.getElementById("depmenulayer").style.disp lay="none";
}
}
</script>

CSS For The Layer and List
====================
#depmenulayer ul
{
margin: 5px;
padding: 0;
}
#depmenulayer ul li
{
display: inline;
}

#depmenulayer li a
{
float: left;
text-decoration:none;
width: 13em;
}

Layer Code
====================

<div id="depmenulayer" onmouseout="javascript:depMenuTog()"
style="display: none">
<ul>
<?php
for ($i=1;$i<=sizeof($dep_menu_list);$i++)
{
echo "<li\"><a href=\"#\">".$dep_menu_list[$i]['name']."</a></li>\n";
}
?>
</ul>
</div>

I had this same issue years ago.
IIRC, it had to do with the sizing of the block where the links and
images are housed in.
Also double check and make sure that any sublevels are properly
closed.
