Known bugs!

There is a bug in the current PyGame release that prevents this example from working. But if you check out the latest PyGame version from CVS it should work just fine!

There is also a workaround to this bug. You have to do a double unlock() after the using pygame.surfarray.array_colorkey() method on an image.
