Detecting a popup blocker blocking in level medium
<p>I am using window.open in order to detect popup blocker
Its works in ie9 for Blocking level: High  but not for Medium
In Medium Level the popup is not null.</p>

<pre><code>var popup = window.open('popup.htm', '_blank', 'width=1,height=1,left=0,top=0,scrollbars=no');
if (popup != null &amp;&amp; popup.closed == false) {
    popup.close();

    window.open('myPage.aspx', '_blank', 'width=500,height=500,left=0,top=0,scrollbars=no');

}
</code></pre>

<p>How can I solved this problem?</p>
