Focus Lost when Dragging JInternalFrame?

Question

Hopefully this should be a simple question:
I have a JInternalFrame with numerous simple components like JTextFields.
When I click the title bar, or click and drag the Frame, the JTextField that had focus prior to that clicking loses focus. Focus goes to the Main Frame window, and if I use setFocusable(false) on the main frame, focus goes nowhere (getFocusOwner() == null).
I want focus to remain in the same component (the JTextField) when clicking on the title bar and when dragging. How do I do this?
I'm using jdk1.4.1_01. Thanks for the help!

I HAVE AN ANSWER!!!
First of all, when you click on the JInternalFrame's title bar, I was losing focus. To fix this, I added a mouse listener to the title bar. I then reset my focus on a mouse clicked event. To find the title bar, I did the following:
private BasicInternalFrameTitlePane findTitleBar()
    Component[] comps = this.getComponents();
    for (int i = 0; i < comps.length; i++)
         if (comps[i] instanceof BasicInternalFrameTitlePane)
              return (BasicInternalFrameTitlePane)comps;
return null;
If the findTitleBar method doesn't return a null, add a mouse listener to it. In the mouseClicked method, reset your focus. I found by using the SwingUtilities.invokeLater, it worked better. So my mouseClicked method looked like:
public void mouseClicked(MouseEvent  e)
   initFocusFor(getFocusComponent());
public void initFocusFor(final JComponent comp )
   if (comp == null)
      return;
   SwingUtilities.invokeLater(new Runnable()
     public void run()
        comp.setRequestFocusEnabled( true );
        comp.requestFocusInWindow();
}Now, for the resizing and dragging.... I was losing my focus on that as well. I believe my desktop manager was getting the focus on resizing and dragging. So, on my subclassed desktop manager, I just added logic to reset my focus on the JInternalFrame on the following methods: endDraggingFrame and endResizingFrame.
Hope this helps someone else.
