Thank for your help,
But it is not working, instead the NVIZ is 'halted'. I wonder is it
because I use Leopard?
Because other vector command like v.digit -n map=newmap bgcmd="d.rast
map=rastermap" for vector tracing also could not start.
I try in IMac using Tiger, the v.digit is working fine.
Any enlightenment? I gladly appreciate.....
