Pygame Crashes when adding graphics without a error
<p>So it seems like every time I run pygame, it crashes when I try to add graphics.  For example, this code works:</p>

<pre><code>import pygame, sys
pygame.init()
screen = pygame.display.set_mode([640, 480])
#screen.fill([255,255,255])
#pygame.draw.circle(screen, [255,0,0],[100,100], 30, 0)
pygame.display.flip()
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
pygame.quit()
</code></pre>

<p>However, when i remove the pound signs, the pygame window will flash open and then close immediately and a crash report appears.  Python doesn't identify any errors in my code either.  Can someone please point out why having the screen.fill and the pygame.draw lines causes pygame to crash.</p>

<p>Im using a mac and python 2.7.9</p>
