One of our students has problems using i.class in grass 4.0
and 4.1. After drawing a training site at the `define region'
prompt, he returns to the main menu and selects `analyze region'.
The system crashes with a data error:
	error reading from graphics driver

Does this mean that the XDRIVER can't write the coordinates of
the training site to the i.class program? What can we do about it?
