i must be doing something veru stupid somewhere because it doesnt do it 
properly.

class drawSprite():
    def __init__(self, bgcolor, height, width):
        self.image = pygame.Surface((height, width)).convert()
        self.image.set_colorkey(bgcolor, pygame.RLEACCEL)
        self.image.fill(bgcolor)

	self.color = library.randomRGB()
        for x in range(4) :
            self.pts.append(library.randomPoint(height, width))
        pygame.draw.polygon(self.image, self.color, self.pts, 0)

To render the surface on the stage I am deleting the image (fill with 
background color its old position on screen), I calculte the new rect 
and then I blit the self.image again on to the screen surface. Finally I 
update the rects.

I have another example where I use an imported image. I just realised 
that they are transparent to the screen, so if i change the background 
color they keep transparent but if I move one on top of the other they 
are actually not transparent and they cover the other images. So rather 
their transparent areas have the color of the background.

any ideas about what could i be doing wrong? or maybe i need some more 
complex system?

thanks again!
