Strange... And the odd thing is that it *does* work to begin with...
it only stops working after a while. And I do blit an image onto the
screen in the beginning too... (Except that doesn't use transparency.)

The effect is really unfortunate, since the text looks extremely ugly

You mean a screenshot could help? (I could put the entire code
base/data dir in a tarball somewhere, if you'd like to try it out and
see if it's just my installation that's acting up or something...)

Err... Yes, of course. Thanks. I've just been playing around with
various versions. (It's a bit like my PostScript code; messing around
with coordinate calculations until it's completely unreadable :)

(BTW, in case you're interested: I'm planning on using PyGame for
developing a small game in one of the chapters in my upcoming book
"Instant Python" :)
