[GRASSLIST:5036] Re: GRASS 5.0; NVIZ visualation tool: problems starting under SuSE 8.1

[Markus Neteler]

Hi,

below problem is fixed in CVS. It will appear in 5.0.1.
You can also modify the code yourself, see

/usr/local/grass5/etc/nviz2.2/scripts/widgets.tcl

search round line 204 for
   if {$val < $res } {
and change it to
   if {$val < $res || $res == 0} {

This may help,

 Markus
