mousePressed() method is always called twice
instead of once. Source of MouseEvent is Canvas
component.

-------------------------------------------

class myMouseAdapter extends MouseAdapter{

 public synchronized void mousePressed(MouseEvent me){
  System.out.println("mousePressed() entered");
  int md = me.getModifiers();
  int clickedX = me.getX();
  int clickedY = me.getY();
  Enumeration men = MapObjectTable.keys();
  while(men.hasMoreElements()){
        Node nd = (Node)men.nextElement();
        if((clickedX >= nd.cx) && (clickedX <= (nd.cx + nodeWidth)) &&
           (clickedY >= nd.cy) && (clickedY <= (nd.cy + nodeHeight))){
           Object obj = MapObjectTable.get(nd);
           MapObject mobj = (MapObject)obj;
           if((md == me.BUTTON2_MASK) || (md == me.BUTTON3_MASK)){
              System.out.println("mouse right button is pressed");
              String mobname = mobj.getName();
              postMapObjectEvent(mobj,mobname);
             }
           else{
              setCurrentMapObject(mobj);
              MapObjectTable = null;
              try{
                  lineends = mobj.getManyToThis().size() +
                             mobj.getPeers().size() +
                             mobj.getThisToMany().size();
                 }
              catch(Exception e){
                 }
              LEnd = new LineEnd[lineends];
              System.out.println(mobj.getName()+" clicked");
              constructNodes();
             }//md
          }

      }
