[R] scatter3d: problem with spheres-color

Dear List,
I don't get scatter3d to color the sheres according to the '|' argument.

library(car)
scatter3d(prestige ~ income + education|type, data=Prestige)

The spheres on my screen are all colored the same and they are not
conditional on Prestige$type.
On the other hand: Fit3d and Ellipse3d are colored according to the
group argument.

rgl_0.92.879
car_2.0-12
R version 2.15.0
i686-pc-linux-gnu (32-bit)

I checked this under windows and: here they are colored according to  
'Prestige$type'.
Hmm? What goes wrong here, any ideas?

thanks,
René
