thanks but that's not it...
on IE 7 it shows that there's an error on line 48 where this is
<script type="text/javascript">if(window.attachEvent) { window.attachEvent("onload", function() { cssmw.intializeMenu('cssmw',{select_current: 0, orientation: 1}); }); } else if(window.addEventListener) { window.addEventListener("load", function() { cssmw.intializeMenu('cssmw',{select_current: 0, orientation: 1}); }, true); }</script>
