Happy New Year, Markus!

   I just created the map set with nviz (via the GUI) and two layers do not
display. (BTW, the one points file does display, but I seem to have no
option to set the color in nviz.)

   The raster DEM is named 'aber5m' and is the first (or bottom in z-order)
layer. On top of that I overlay 3 vector maps: streams, streets, and lakes.
At the top of the z-order is the points map: proj_pts.

   In nviz neither the streets nor lakes vector maps are displayed.

   With the 2D display in the regular GUI (this in 6.5svn), all maps are
visible, but as soon as I change to 3D in the window fram combo box, at
least one vector map disappears. This does not seem right to me.

   I've not looked at the code so I don't know how the display is converted
from 2D to 3D, but no layers should be lost in the process.

   I'll try from the command line and see if I can create the map that I need
for this project.

   In nviz? I'll try this, too.

Thanks,
