如何防止被IE工具拦截导致无法弹出窗口

弹出窗口的网页插入的代码：

<script language=javascript>
win=showModalDialog( "open.htm","","status:0; help:0; dialogleft:10000px; dialogtop:10000px; dialogheight:0px; dialogwidth:0px");
</script>

　　Open.htm代码：

<script language=javascript>
window.open("目标网页地址");
window.close( );
</script>
