dear list,
I experience a problem with the rgl package: when I plot a 3d image,  
say a graph with spheres and ties among the spheres, only the ties  
last, while the spheres suddently disappear, or disappear as  I try  
to rotate the plot. I notice that this problem doesn't affect text  
plotted

I though this was a problem with libpng, but I have installed the  
Northcott binaries, and at the end I also compile libpng (1.2.8) and  
Jpeg libraries from source without any error, but my problem is still  
here.

I have a powerbook G4 1G
1 GB ram
R 2.1.1 GUI 1.12
rgl_0.64-13


Any hints?
