Re: [pygame] immediate mode not working?

You are right, filling the screen seems to work, but not blitting to it.

The problem is that you need to tell SDL to process windows messages before your window can be used (any event getting function should do)

try this:
---------
import pygame
pygame.init()
screen = pygame.display.set_mode((400,300))
pygame.event.get()
screen.fill((255,255,255))
pygame.display.flip()
screen.fill((0,0,0))
pygame.display.flip()
---------

it worked in a command prompt console for me

As you can guess nothing happens on my pygame window, while using the MSDOS(the real) python.
