    jScrollPane1.getViewport().add(jTextArea2, null);
  //Overridden so we can exit when window is closed
  protected void processWindowEvent(WindowEvent e) {
    super.processWindowEvent(e);
    if (e.getID() == WindowEvent.WINDOW_CLOSING) {
      System.exit(0);
  void jScrollPane1_mousePressed(MouseEvent e) {
    jTextArea2.append("mouussee pressed");

Change jTextArea2.setPreferredSize() to jScrollPane1.setPreferredSize(). As it stands now, you are telling the text area that you don't want it to change size, if at all possible, so it doesn't.
