Hur får man en CSS hoverlist att funka i IE

Är det nå´n som vet hur man kan göra om denna meny så att hover-funktionen fungerar i IE?

HTML
<div id="navcontainer">
<ul id="navlist">
<li id="active"><a href="#" id="current">Item one</a> 
<ul id="subnavlist">
<li id="subactive"><a href="#" id="subcurrent">Subitem one</a></li>
<li><a href="#">Subitem two</a></li>
<li><a href="#">Subitem three</a></li>
<li><a href="#">Subitem four</a></li>
</ul>

</li>
<li><a href="#">Item two</a></li>
<li><a href="#">Item three</a></li>
<li><a href="#">Item four</a></li>
</ul>
</div>

CSS
ul#navlist { font-family: sans-serif; }

ul#navlist a
{
font-weight: bold;
text-decoration: none;
}

ul#navlist, ul#navlist ul, ul#navlist li
{
margin: 0px;
padding: 0px;
list-style-type: none;
}

ul#navlist li { float: left; }

ul#navlist li a
