      java version "1.3.0"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
      Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)

      When JTextField has set InputVerifier which shows dialog (reporting invalid
      input) and user puts some data into such text field and then clicks on button,
      the button remains in pressed state after dialog is closed. When you roll mouse
      over the button. If mouse pointer is outside of the button, it looks normal. The
      button sometimes behaves correctly in the first click onto button. Next try
      always brings described behaviour. It is the same on WinNT 4.0, JDK 1.3.1.

                + "after closing this dialog.\nIt sometimes behaves correctly "
                + "for the first time\n but repeating action brings incorrect "
                + "behaviour of button.";
            JOptionPane.showMessageDialog(null, message , "invalid value",
            return false;
