Good. Sometimes 'devel'-lists are meant for those developing on a certain
product. Questions from 'users' on those lists are not always welcome.

Ok, because whatever I tried feeding to it the function just returned 0.
Well, I can manage without it, as I just aim for 1024x768 fullscreen or
windowed (togglable by the player). That resolution should be available on
almost any hardware today, and if it isn't I think Python is too slow on
it anyway... :-)

Always a pioneer.

This sounds good. I just started using Python 2.0, and the old modules
don't work with it, including pysdl. So far I use 1.52 for the development
of the parts that use pysdl, and 2.0 for the parts that rely on the new
XML handling. It would be nice if there would be a Python 2.0 version of
pysdl some day. I have no idea as to how hard it is to do the port, but I
hope it's not impossible?

I need only one resolution, 1024x768. I merely wanted to be able to check
the possibility of using that mode before having pysdl try to initialize
it. Later I think multiple resolutions should be possible, but that is in
a later version. One has to start easy and get something simple that works
and then build upon it.

Thanks a lot for your help!

Btw, I figured out how to use transparency. My png:s have a transaprent
color, so it was just a matter of calling the method set_colorkey() (if I
remember the name correctly), and it all worked ok.
