Hi Gustavo,

I was interested by your email, so I tried reproducing the problem
with a simple pygame game and encountered the same issue.  Not sure
what's going on yet though.  The only reference to this I found was
this message from Fernando some 7 years ago :(

Sounds like there were problems though. I don't know if anyone else
has resolved them.
