[Pythonmac-SIG] weird pygame problem on 10.4

[altern]

hi all

I just upgraded my old mac laptop to 10.4.8 from 10.3.9. I am running 
pygame + pyopengl scripts and I find this weird error that did not 
happen on 10.3.9. The 'canvas', the surface were the drawing happens it 
is misplaced within the window by 100 px to the right and 100 px to the 
top. So I get a 100 px wide empty band on the left bottom of the window.

If I run the same script using wxPython instead of pygame to handle the 
window events there is no problem at all.

The funny thing is that neither the pygame or the pyOpenGL examples have 
this problem, so it must be my code. But I dont really know where to 
start debugging from.

I am running python 2.4 and i installed all the stuff from
http://www.pythonmac.org/packages/py24-fat/index.html
including :
python-2.4.4-macosx2006-10-18.dmg
pygame-1.8.0pre-py2.4-macosx10.4.zip
PyOpenGL-2.0.2.01-py2.4-macosx10.4.zip

any hints would be very much appreciated

thanks!
