Modal dialogs don't paint in full screen mode

[Mike Westerfield]

I'm using gd.setFullScreenWindow() on Windows XP 1.5.2600, JDK
1.4.2_03 to enter full screen mode. Once there, I'm creating a modal
dialog. I've tried both JOptionPane and JDialog. The frame of the
dialog is not painted, and if the dialog is dragged, the entire dialog
vanishes.

Does anyone know why this fails, or can you suggest a way to display a
full screen window on Windows XP that still supports modal dialogs?
