It should be the frame.

Are you using a PNG monitor (d.mon start=PNG), or immediate rendering
(GRASS_RENDER_IMMEDIATE=TRUE; enabled by default on Windows)?

If it's the latter, commands which rely upon persistent state (e.g. 
d.frame, d.font) don't work; the driver is re-initialised for each
command. In 7.0, you can use the GRASS_FRAME environment variable to
specify the frame for a command, but there isn't any equivalent in
6.x.
