Try:

<head>

<script language="JavaScript1.1"><!--
var debug = true;

function left(e) {
    if (navigator.appName == 'Netscape' && (e.modifiers & Event.SHIFT_MASK) && (e.which == 1)) return false;
    else if (navigator.appName == 'Microsoft Internet Explorer' && window.event.shiftKey && (event.button == 1)) {
        alert('Denied');
        return false;
    }

    if (debug) alert('Allowing mousedown event to proceed...');
    return true;
}

document.onmousedown=left;
if (document.layers) window.captureEvents(Event.MOUSEDOWN);
window.onmousedown=left;
//--></script>

</head>

<body>
