Re: [pygame] This program breaks on my Linux

[B W]

Argh! pygame.mixer.quit() is hanging.

('keydown', 'escape')
Exit progress: begin
Exit progress: pygame.display.get_init()
Exit progress: pygame.display.get_surface()
Exit progress: screen.unlock()
Exit progress: pygame.display.set_mode((16, 64))
Exit progress: pygame.display.flip()
Exit progress: pygame.display.quit()
Exit progress: pygame.mixer.quit()

Gumm
