Swing JPanel PaintComponent Issue

I have a JFrame that I have undecorated and in full screen mode. To
draw on the screen, I add a JPanel and draw on that and go for a
setVisible(true). Then, I do what I need and do a setVisible(false)
and go forward.

Sometimes, though, my application will just hang and not paint
anything - at various `screens' ... I'm not doing any threading stuff
in my code, so I don't think that's it. Any ideas?

Thanks
