YUI panel在IE不能正常显示

[alinglau]

各位大侠
本人用YUI写了一个在页面弹出popop,在FIREFOX能正常显示，但在IE上不能正常显示，样式拿不到，请问是什么原因呢？
代码如下：

<a id="showBubble" href="javascript:popupSeatMapWindow();">Show Bubble</a>

<div id="divSeatMapPopup">
        <div class="hd"><div class="tl"></div><img src="img/tip_icon.gif" /><span>Seat Map</span><div class="tr"></div></div>
        <div class="bd">This is a Panel that was marked up in the document.<a href="" onclick="YAHOO.test.container.myPanel.hide()">Close Window</a></div>
        <div class="ft"><div class="bl"></div><div class="br"></div></div>
</div>


<script type="text/javascript">
    function popupSeatMapWindow()
    {    
        
        YAHOO.namespace("container");
        YAHOO.test.container.myPanel = new YAHOO.widget.Panel("divSeatMapPopup", 
        { width:"720px", height:"501px", visible:false, constraintoviewport:true, underlay:"shadow", fixedcenter:true, modal:true, draggable:false, close: true} );
        YAHOO.test.container.myPanel.render(); 
        YAHOO.test.container.myPanel.show();    
    }
</script>
