Every time you repaint it only draws what you tell it to, so how bout something like this:
Add a vector to store the rectangles:
Vector<Rectangle> rectangles = new Vector<Rectangle>();In paint when you create a new rectangle add it to the vector:
         public void paint(Graphics g) {
          //recover Graphics2D
          Graphics2D g2 = (Graphics2D)g;
          g2.setColor(color);
          if(drawObject) {
               //create Rectangle Object
               myRectangle = new Rectangle(startX,startY,width,height);
               rectangles.add(myRectangle);
          } else if (moveObject) {
               myRectangle.setLocation(x2,y2);
          for (int i = 0; i < rectangles.size(); i++) {
               g2.draw(rectangles.get(o));
      }When you check to see if the click is in a rectangle check them all:
     //Check to see if mouse is pressed in the current rectangle.
     for (int i = 0; i < rectangles.size; i++) {
          if(rectangles.get(i).contains(x1,y1)) {
               //move the object instead of moving it
               drawObject = false;
               moveObject = true;
               myRectangle = rectangles.get(i);
     }Just briefly looked over your code so there may be a few other places you need to change. Also if you post code its a lot easier to read if you put it in code tags.
