hi again.. the problem seemed fixed, but only because it shows and goes away quite randomly.. and the above code doesn't work for me! I don't know what you mean by randomly, and if you don't give us any indication of failure conditions we can't help you figure out why the code doesn't work. -Luke
Re: [pygame] refresh problem
Lots of people forget to put 'pygame.event.pump()' in the main loop. Try that, see if it stabilizes.

[pygame] refresh problem
hi to all! this is my first post in pygame (windows xp, python 2.5). i've started using pygame some days ago and after a bit of coding i'm completely stuck. the problem is that even the simpliest code like import pygame from pygame.locals import * pygame.init() screen = pygame.display.set_mode( (640,480) ) done = False while not done: pygame.display.flip() for event in pygame.event.get(): if event.type == QUIT: done = True get the game window to freeze. it just doesn't update and acts strangely. the window is like transparent, it makes me see what is behind it. if i minimize it and then reopen it, it shows the content, but if i drag it around the screen, it sort of collects the images it overlaps.. i've tried various code to get around the problem, like various flags in set_mode, flip and update and event pumping but nothing seems to work. it shows no problem in fullscreen mode, though. any idea? thanks in advance, gustavo

That's really all I can think of, your code looks fine to me. -Luke

(again, i'm working under windows xp) don't right-click and choose edit with IDLE. instead, open IDLE from the start menu and load your files from within IDLE (should be in 'recent documents') there's some problem with IDLE and using the separate subprocess that only comes up when you right click and edit, so the developers made it to where if you choose that option from the context menu IDLE boots with subprocess turned off. You can also edit the code for the 'edit with IDLE' menu item to get around this, but this isn't recommended because some people will run into whatever problem there is. I personally haven't had any problems with re-enabling the subprocess. -Luke
