<script type="text/javascript">
var message = "Right Click Have Been Disabled!";
function clickIE() { if (document.all) { alert(message); return false; } }
function clickNS(e) {
if
(document.layers || (document.getElementById && !document.all)) {
if (e.which == 2 || e.which == 3) { alert(message); return false; }
}
}
if (document.layers)
{ document.captureEvents(Event.MOUSEDOWN); document.onmousedown = clickNS; }
else { document.onmouseup = clickNS; document.oncontextmenu = clickIE; }
document.oncontextmenu = new Function("return false")
</script>

and how to add feature of displaying I.P address of person who right clicked ?
