<script language=javascript>  
 <!--  
   
 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>
