      Reproduced on Redhat Enterprise Linux 4 (Update 4) with 1.6.0-b105.

      On MAWT TextArea or TextField, cursor keeps blinking after focus moved to a native window.

      Test instruction is as follows:
      1. Compile and launch the sample code with MToolkit.
      $ javac TextAreaTest
      $ AWT_TOOLKIT=MToolkit java TextAreaTest
      => Two TextArea components will appear.

      2. Move focus to "TextArea 1".

      3. Move focus to another native window, like terminal.
      => Cursor is still blinking. <= Problem.

      4. Move focus from the native window to "TextArea 2".
      => Both TextArea 1 and 2 show blinking cursor. <= Problem.

      Expected result:
      Cursor should be pale color and stop blinking, after focus loses.

      Focus change between these TextArea components, it works as expectedly.

      Additional Information:
      Motif's text widget doesn't get FocusOut event.

      The problem didn't occur on Java5. It introduced from Java6.

                      frame.add(new TextArea());
                      frame.setSize(300, 100);
                      frame.setVisible(true);
              }
              public static void main(String[] args) {
                      TextAreaTest t1=new TextAreaTest("TextArea 1");
                      TextAreaTest t2=new TextAreaTest("TextArea 2");
              }
