When called, this script sets the document variables X and Y to the location of the mouse relative to the uppermost left pixel of the webpage.

    var IE = document.all?true:false;
    if (!IE) document.captureEvents(Event.MOUSEMOVE)
    document.onmousemove = getMouseXY;
    
    var X = 0;
    var Y = 0;
    
    function getMouseXY(e) {
      if (IE) { // grab the x-y pos.s if browser is IE
        X = event.clientX + document.body.scrollLeft;
        Y = event.clientY + document.body.scrollTop;
      } else {  // grab the x-y pos.s if browser is NS
        X = e.pageX;
        Y = e.pageY;
      }
      
      if (X < 0){ X = 0; }
      if (Y < 0){ Y = 0; }  
      
      return true;
    }
