Javascript "member not found"
<p>I have a web page that has some links to pdf files that open in a new scrren.  If I click one of the links the new page opens fine.  If I click on another link while that page is open it replaces the page with the new page which is fine, however it throws a JS erre saying  "member not found"</p>

<p>HTML:</p>

<pre><code>helpMenu.add( new AnchorMenuItem("User Guide", "javascript:openHelpWindow('../html/help/user_guide.html');") );
helpMenu.add( new AnchorMenuItem("FAQ", "javascript:openHelpWindow('../html/help/faq.html');") );
helpMenu.add( new AnchorMenuItem("Features", "javascript:openHelpWindow('../html/help/features.html');") );
helpMenu.add( new AnchorMenuItem("Overview", "javascript:openHelpWindow('../doc/Overview.pdf');") );
helpMenu.add( new AnchorMenuItem("Actual Info Guide", "javascript:openHelpWindow('../doc/ActualInfoGuide.pdf');") );
</code></pre>

<p>JS</p>

<pre><code>/**
* Function to open the pop-up windows that the radio button
 * or select box options will be chosen from.
 */
function openHelpWindow(url)
{
    var w;
    if (isBrowserNetscape)
    {
        // Netscape
        w = window.open(url, "MSSTHelp", "resizable=yes, scrollbars=yes, menubar=no, location=no, toolbar=no, height=700, width=900, screenX=100, screenY=100");
    }
    else
    {
        // IE
        w = window.open(url, "MSSTHelp", "resizable=yes, scrollbars=yes, menubar=no, location=no, toolbar=no, height=700, width=900, left=100, top=100");
    }
    w.focus();
}
</code></pre>

<p>The error is at <code>w.focus();</code></p>
