Silent Page Refresh... (no Browser Click Sound In Win/IE)

Between the head tag of html:

<script type="text/javascript" src="js-bin/silent_refresh.js"></script>
In a javascript named silent_refresh.js: (make sure the script is in a folder called 'js-bin')
window.onload = doLoad;

function doLoad()
{
setTimeout( "refresh()", 60*1000 );
}

function refresh()
{
window.location.reload( false );
}

The page will refresh every 60 seconds - Just alter the 60 to whatever time you require.
