function   ie()   {
if   (navigator.appName== "Microsoft   Internet   Explorer ")   {
return   true;
}   else   {
return   false;
}}

function   showmenu(){
if   (ie()){

var   rightedge=document.body.clientWidth-event.clientX
var   bottomedge=document.body.clientHeight-event.clientY


if   (rightedge <menu.offsetWidth)
menu.style.left=document.body.scrollLeft+event.clientX-menu.offsetWidth

menu.style.top=document.body.scrollTop+event.clientY

menu.style.visibility= "visible "
}
return   false
