[GRASSLIST:2611] Some problems in vector analysis

[Maliheh]

Hello dear list,
I have some problems in 5.7, I wish you help me...

1. Sometimes that I use of d.what.vect, it shows me:
     Buttons
     Left:  what's here
     Middle: toggle flash color
     Right: quit
   But when I click left key of the mouse on the map
   nothing happens and if I do it again it shows:
     Broken pipe
   and quit from d.what.vect

2. When I am successful on use of d.what.vect, I have
   these values on my street map:
     ...
     Type: Point
     field: 1
     category: 6
     ...
     -----------------------
     ...
     Type: Point
     field: 1
     category: 160
     ...
    
    Now I want to find the best path between two
points 
    so I use:
      v.net.path input=Teh_Vect output=t2 type=line
afield=1 nfield=1
    It shows:
      Vector 't2' already exists and will be    
overwritten.
      Building graph:
      Registering arcs ...  100%
      Flattening the graph ... done.
      Graph was built.

    Now I write :
      6 160   (Is it correct?)
    But nothing happens.
    
Would you please tell me my wrong and explain me more
about v.net.path?

Thanks a lot

Maliheh
