I created a `JFrame` and and a `JWindow`. My problem is that when I click on another application my `JFrame` passes behind the application but not my `JWindow` which remains always on top.
I tried to call `setAlwaysOnTop(false)` on my `JWindow` but this doesn't change anything.
I would like that the `JWindow` "follows" the `JFrame.`

Here's my test code:

```
public class WindowAlwaysOnTop {
    public static void main(String[] args) {
        final JFrame frame = new JFrame();
        frame.setSize(new Dimension(400, 400));
        final JWindow window = new JWindow(frame);
        window.setAlwaysOnTop(false);
        window.setSize(new Dimension(200, 200));
        frame.setVisible(true);
        window.setVisible(true);
    }
}

```
