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>
