Works in NS 7.1 :-)
Suggestions:
Your pages, eg. rpanel.html, is neither correct HTML 4.01 nor XHTML 1.0, see http://validator.w3.org for details.
The embed element is not part of the HTML 4.01 Specification, and is therefore not a W3C standard. Also, http://devedge.netscape.com/viewsource/2002/markup-and-plugins/ recommends "in order to overcome the shortcomings that you can't nest object elements in IE and that there isn't a way you can simply use one object element in a cross-browser way (with architecture specific obtainment mechanisms), the best course of action is to dynamically write object elements based on architecture. For example, on browsers that support ActiveX, such as IE, create an object element with a classid attribute, and on browsers that support the Netscape Plugin architecture, use a MIME type."
JavaScript Expample:
<script type="text/javascript">
<!--
if (window.ActiveXObject)
{
// browser supports ActiveX
// Create object element with
// download URL for IE OCX
document.write('<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"');
document.write(' codebase="http://download.macromedia.com');
document.write('/pub/shockwave/cabs/flash/swflash.cab#version=5,0,0,0"');
document.write(' width="366" height="142" id="myFlash">');
document.write(' <param name="movie" value="javascript-to-flash.swf">');
document.write(' <param name=quality value=high>');
document.write(' <param name="swliveconnect" value="true">');
document.write('<\/object>');
}
else
{
// browser supports Netscape Plugin API
document.write('<object id="myFlash" data="javascript-to-flash.swf"');
document.write(' type="application/x-shockwave-flash"');
document.write(' width="366" height="142">');
document.write('<param name="movie" value="javascript-to-flash.swf">');
document.write('<param name="quality" value="high">');
document.write('<param name="swliveconnect" value="true">');
document.write('<p>You need Flash for this.');
document.write(' Get the latest version from');
document.write(' <a href="http://www.macromedia.com/downloads">here<\/a>.');
document.write('<\/p>');
document.write('<\/object>');
}
