Well, I do. But I made some work manually because I have custom
installation of Python and wxPython for other project.

Sure, I add layers through 'Add vector' button usually, but I'm trying
to follow book in this case :)

Well, OK. I will try to find time and look at the code by myself. The
problem was that I was not sure if it is bug or feature.

Thanks! The main goal of my returning to GRASS is developing scripts to
automate process of creaing maps. That's why I am interested
to run commands.

Oops!  I miss that. Thanks!

Thanks again. As far as I understand, I can change this setting through 
Config ->GRASS working environment menu. Can't I?
