Ok, here is the code... I didn't write it...so I'm leaving the credit on there.. And please if you use it, dont remove the credit line. Script works with Netscape 4 AND Internet Explorer 4+

Code:
<script language=JavaScript>
<!--

//Disable right click script III- By Renigade (renigade@mediaone.net)

var message="";
///////////////////////////////////
function clickIE() {if (document.all) {(message);return false;}}
function clickNS(e) {if 
(document.layers||(document.getElementById&&!document.all)) {
if (e.which==2||e.which==3) {(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>
