Yep. Pretty minimal: make a JTree, put it in a container, paint it,
Boom! Code follows. OS is Linux kernel 2.4.19. Distro is Slack. JVM
and all Java tools are Sun's latest J2SE 1.4.1 (though I tried with
1.4.0 too, no joy). Display is pretty ordinary: 800x600x8bits.

Thanks for looking.

	fr.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

And for a hefty dose of additional fun and excitement, we bring you....
