function getEvent()
{
var i = 0 ;
if(document.all){
return window.event;
}

func = getEvent.caller;
while(func != null)
{
var arg0 = func.arguments[0];
if(arg0)
{
if(arg0.constructor == MouseEvent)
{
return arg0;
}
}
func = func.caller;
}
return null;
}

function buttonOver(e)
{

}
else
obj.style.background = "#FFFFFF";
}
