no d.* will work from the output window. You cannot interact with the 
gis.m Display window through commands, only through the GUI.

x-monitors do not work in Windows. You have to work through the GUI, or 
directly on the cmd.exe (or msys) command line (don't think this works 
via the output window) using GRASS_RENDER_IMMEDIATE=TRUE.
