artdialog 4.1.6 在ie6 下a标签和button按钮、input框表现不一致

[GoogleCodeExporter]

artdialog 4.1.6,
<a class="trash-index" href="javascript:;" onclick="addProPrice()">ww</a>
<button onclick="addProPrice()">xx</button>
<input onclick="addProPrice()" value="" />
后边两种方法都能有弹出框出现，而第一种则是一直在loading�
��面。

//新增
function addProPrice(){
    openWindow('新增采购价格','business?service=page/ProdPurchasePriceAdd',600, 240);
}

function openWindow(title,url,width,height){
    art.dialog.open( url , 
        {
        title: title,
        lock: true,
        width: width+'px',
        height: height+'px',
        opacity:.2
    },
    false);
}
