I understand why it's not working on Windows.  Microsoft's OpenGL  
software renderer is very primitive, and does not have the  
capabilities needed for shadows.  Depending on your video card, you  
might be able to get shadows using  
kQ3DrawContextPropertyAcceleratedOffscreen.

I think it ought to work on the Mac, though I wonder why you have not  
updated to 10.4.10.
