[GRASS-windows] Features not yet implemented

[Peter Brooks]

Hi... I'm new to GRASS but not to GIS.  Downloaded 6.4, and got to 
grips with the wxPython GUI, which seems a lot more intuitive than 
the TclTk GUI.

I bought the comprehensive (but pricey) 'OPEN SOURCE GIS - A GRASS 
GIS Approach' and am running through the examples but it seems a lot 
of commands don't work in the new GUI... even d.erase comes back with 
"Command 'd.erase' not yet implemented." (although there is a button 
in the map display window that does just that!)

I also run a Mac and the same thing happens with the new GUI on that.

Does anyone know why this is, and when (or in what version) it is 
likely to be fixed?  It is a little disconcerting to a new user 
running through the book (yeah, I know it is Windows, and software on 
that platform is meant to be full of bugs :-)

Many thanks
Peter
