[GRASSLIST:10194] Three questions on ps.map

Hi

I am using ps.map and I have a few questions regarding it. My map is build up with a nomber of vector layers

1) I am getting a frame around the map. Is that possible to avoid?
2) Is it possible to put the units on the scale bar?
3) I have a vector layer with a closed polygon where I just want to draw the outline. I tried using vlines, but then nothing showed up. This may also be some problem with how the layer is defined.
