    function toggleAutoRefresh(cb) {
        if (cb.checked) {
            window.location.replace("#autoreload");
            reloading=setTimeout("window.location.reload();", refresh_time);
        } else {
            window.location.replace("#");
            clearTimeout(reloading);
        }

<!-- add input checkbox in html body -->
<span><input type="checkbox" onclick="toggleAutoRefresh(this);" id="reloadCB"> Auto Refresh</span>

This no longer works in Chrome or Firefox. Still works in IE. Used to work in all three.
