Thank you for your replay. Of course you can clip the vector maps or
create views, but I miss the point why GRASS manage the raster using
the region settings and don't take into account the region settings
for the vector maps. from my point of view It's not consistent...
And ok, let me say that we don't care the consistency, I think that at
least the d.vect command should load only the geometry features that
are contain in the bounding box of MapWindow.
Best regards.
