Problem solved! was: [pygame] Pygame.sprite ignores transparency?

[Wildflower <wildflower@xxxxxxxx>]

Thanks everyone for replying so swiftly!

Brian's advise solved the problem.
The little demo program I put together to post here didn't have the 
transparency issue. So, the fault was in my code and not in Pygame. :p
Who would have thought ? ;)
It turned out I had not called clear() properly. The transparency was 
"lost" because it repeatedly drew the same (immobile) sprite again and 
again, effectively "painting in" the semi-transparent parts.

Cheers,
