[jQuery] [tooltip] image map area not working on ie6

[jQuery] [tooltip] image map area not working on ie6


Hi,
considering this plugin : http://bassistance.de/jquery-plugins/jquery-plugin-tooltip/
I have a tooltip applied on each <area> tag on my image map and it's
working fine with FireFox PC but not with IE6 or IE7.
Here is a sample of my code :
[...]
<script type="text/javascript" src="js/jquery-1.2.3.pack.js"></script>
<script type="text/javascript" src="js/jquery.dimensions.js"></script>
<script type="text/javascript" src="js/jquery.tooltip.js"></script>
<script type="text/javascript">
jQuery(document).ready(function() {
    $('#bigMap area').tooltip({
        track: true,
        delay: 0,
        showURL: false,
        opacity: 0.85
    });
});
</script>
[...]
<div id="bigMap">
<img src="img/map-france-dept.jpg" alt="" border="0"
usemap="#Mapping" />
<map name="Mapping" id="Mapping">
    <area shape="poly" coords="176,20,193,38,196,53,222,56,222,44,187,15"
href="#" title="Nord" alt="" />
</map>
</div><!-- #bigMap -->
Thanks for any help to fix this =)
