I'm assuming you are running this on your Mac, but if you are not, you should try.

Not that I have been running it all that often, but when I run it under Linux I don't believe I have crashed once. On my XP box, I get the same blackscreen, and if I act fast enough and kill the java process I don't need to reboot, otherwise, yeah system reboot.

All very odd.

You could also try running it from your browser to see how that goes.
