It seems to be a bug in certain window managers; dtwm and BlackBox
have both been reported as having problems, fvwm and twm both work.

XDRIVER itself adds geometry constraints when a client connects, and
removes them when the client finishes. This was added to prevent users
from resizing the monitor in the middle of an interactive program
(e.g. v.digit, d.what.*), as the programs can't handle this.

The problem is that certain window managers honour the geometry
constraints even after they have been removed. You can confirm this
using the "xprop" utility.

It's present in 5.0.0 and 5.0.1 (in $GISBASE/scripts).

The initial size of a monitor is determined by the GRASS_WIDTH and
GRASS_HEIGHT environment variables, e.g.

	GRASS_WIDTH=512
	export GRASS_WIDTH
	GRASS_HEIGHT=384
	export GRASS_HEIGHT

Also, if you start the monitor without selecting it:

	d.mon -s start=x0

you should be able to resize it. You then need to select it with:

	d.mon select=x0

However, after this, the problematic WMs won't let you resize it.
