viewing dxf-files in Grass (problem)

Hi there.
I am trying to import some of the files I created with AutoCAD in the dxf-
format to Grass4.1

first I convert with `v.in.dxf' and in the directory ~/dig/ the file is created, and I create support files with `v.support'
2nd. I start a graphics monitor with d.mon (I am working with X-windows)
3th. I open the file with `d.vect', the message screen tells me that all the plotting is done, but I don't see a thing !!!

Who tells me what I am doing wrong ?

thanks
Elwin
