JFrame resize flicker using look&feel

Question

I just discovered JFrame's setDefaultLookAndFeelDecorated. Of course, it works great (refreshing to see it on vanilla windows!), but the frame flickers during mouse resizing. Every pixel the mouse moves, the frame is drawn gray then the previous frame's image is drawn over. Is there any way to stop this?
And is there any way to do dynamic resizing? i.e. The window continuously revalidates&redraws itself while the user is resizing, and not just when the user stops resizing. At the least, is there a way to dynamically resize the border? Otherwise, a gray box (and the flicker) are the only things that shows until the user stops resizing.
Specs: WinMe/JDK1.4.

Run the following complete program and you should get the flicker problem when resizing it. Them dukes be still available! Tell me if you have any idea how to correct it, or how to dynamically resize the "guts" of the window. Thanks.
