window.open tracing - help required

Hello everyone!
I was willing to make a script for my radio not to be realoaded each time user presses any link on the page. I thought I'll create it in popup window, but the site also has embedded radio, so I need it to be hidden or showed depending on that popup window, if it is active div tag will hold some text, if not it will hold that radio. Or to make a script which will popup that window only once through all time user browses my site. In any case I need somehow to trace that opened window, I don't know how to do it AFTER user presses any link and the page being updated. Script doesn't reallize anymore that window was already opened Any help will be appretiated!

Here's part of my script, on which I was working:

Code:

[COLOR=Sienna]<script LANGUAGE='JavaScript'>
<!--
function openWindow() {
    if (!window.window2) {
        window2 = window.open('','windowRef','width=200,height=30,resizable=0,scrollbars=0');
		window2.window.resizeTo(323,50);
		window2.document.write("<object id='WinMedia' classid='CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95' codebase='http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701' standby='Loading Microsoft Windows Media Player components...' type='application/x-oleobject' height='50' width='323'>");
		window2.document.write("<param name='FileName' value='http://server2.digital-webstream.de:10780'>");
		window2.document.write("<param name='AutoStart' value='true'>");
		window2.document.write("<param name='ShowControls' value='true'>");
		window2.document.write("<embed type='application/x-mplayer2' pluginspage='http://www.microsoft.com/Windows/MediaPlayer/' src='http://server2.digital-webstream.de:10780' name='MediaPlayer' autostart='1' showcontrols='1' height='50' width='323'>");
		window2.document.write("</object>");
		window2.closed();	
    }
	
}
-->
