Hamish,

   I must be invoking nviz incorrectly as I run out of memory with 4G on this
system and 182M free. I call nviz this way:

GRASS 6.5.svn (Oregon):~/grassdata/Oregon/beaver_lake > nviz
elev=aber5m,mompano_rast vector=streets,streams points=proj_pts

and see no way to specify colors, symbols, or sizes for the vector and
points file. Regardless, this is the result:

   exit
}"
     (file "/usr/local/grass-6.5.svn/etc/nviz2.2/scripts/nviz2.2_script" line

   Why are the raster files loaded twice each? What can I do to allow nviz to
do its thing?

Thanks,

Rich
