Sorry, missed that. Did you use the osgeo4w installer ?

As long as its a small file, this is ok. Even better is to put 
screenshots on a web site and link to it.

Funny, here in GNU/Linux and with grass6 development version, d.his 
works, but d.vect doesn't. For the latter, I first have to double click 
on the vector layer and click on Apply for the vector layer to appear in 
the Map Display...
Can't try on Windows right now.

I don't know. Maybe due to the fact that d.barscale has some interactive 
code for placement... CC'ing to the wxgui developers for comment.

When direct rendering is "activated", you can type d.* commands at the 
command line and the result is rendered into a file, instead of the 
screen. See

http://grass.osgeo.org/grass64/manuals/html64_user/variables.html#dirrend
and
http://grass.osgeo.org/grass64/manuals/html64_user/pngdriver.html

To use this, you have to use GRASS via the command line.

Click on the button circled in red on:

You then get a menu, of which one choice is "Add HIS layer" which opens 
the d.his dialogue window and adds a layer to the GIS Manager.

Well, for windows, the bleeding-edge one is probably much more stable 
than any older ones.

You could try using the gis.m GUI instead of the wx GUI. For that you 
need to find your .grassrc6 file (normally in your home directory, which 
under windows is often in c:\Documents and settings\UserName and change 
the setting of the GRASS_GUI variable to tcltk and then restart GRASS.
