how to use swing/awt controls in a window that uses double-buffering?

hello!

i'm using a JFrame with enabled double-buffering. the window itself
owns several JInternalFrames. my problem is that when double-buffering
is enabled, the internal frames are invisible, with an exception that
they flicker for few milliseconds when i move the mouse over their
position.

is it possible to use internal frames or controls at all along with
double-buffering?
if not, what else could be done?

thanks in advice!

Can you post a simple example that demonstrates your problem?

well, it is a _lot_ of code. i try to reduce the amount:

////////////////////////////////////////////////////////////////
// main window (extends JFrame) c-tor contains:

    // ...
    // add JInternalFrames to 'this'
    // ...

    setIgnoreRepaint(true); // skipping this doesn't help
    setExtendedState(JFrame.MAXIMIZED_BOTH);
    setVisible(true);
    validate();

    createBufferStrategy(2);
    bufferStrategy = getBufferStrategy();

////////////////////////////////////////////////////////////////
// main loop of the rendering thread contains:

    g = (Graphics2D) bufferStrategy.getDrawGraphics();

    g.clearRect(0, 0, getContentPane().getWidth(),
        getContentPane().getHeight());

    // ...
    // draw lots of BufferedImages using d.drawImage(...)
    // ...

    bufferStrategy.show();
    g.dispose();
    ++framesRendered;
