Problem removing components from JLayeredPane

Question

Hi all,
I have a problem showing and hiding components on a JLayeredPane. It goes Something like this:
In my application I have a button. When this button is pressed I use getLayeredPane to get the frames layered pane. I then add a JPanel containing a number of labels and buttons onto that layered pane on the Popup layer. The panel displays and funcitons correctly.
The problem comes when I try to remove the panel from the layered pane. The panel does not dissappear and I am no longer able to click on anything else in the frame!
If anyone has any ideas how to get around this or what the problem might be I'd be very greatful to hear it. Sample code follows:
      * Called when the button on the frame is pressed:
      * @param e
     public void actionPerformed(ActionEvent e)
                JLayeredPane mLayredPane = getLayeredPane();
          int x = 0, y = 0;
          Container c = this;
          while (true)
               c = c.getParent();
               if (c != null)
                    x += c.getLocation().x;
                    y += c.getLocation().y;
                    if (c instanceof JRootPane)
                         break;
               else
                    break;
          mPanel.setBounds(x, y, 235, 200);
          mLayredPane.add(mPanel, JLayeredPane.POPUP_LAYER);
//And when a listener fires from the panel I use
mLayredPane.remove(mPanel);
//To remove it from the layered pane and in theory return the
//app to the state it was before the panel was displayedThanks again...

The problem is you only removed it within the program, without actually removing it from the display. If that makes any sense, or whether thats your problem at all.
If you are only using this line.
mLayredPane.remove(mPanel);
I think if you tell it to repaint and revalidate it should work, though i have never used LayeredPane.
mLayredPane.repaint();
mLayredPane.revalidate();
