empty monitor in i.pr.classify

[arocha1980]

While using i.pr.classify i found 2 bugs.

1- from GUI it's not possible to run i.pr.classify due to the fact that it needs to have d.mon x0

2 (and this one is CRITICAL) First I do d.mon x0 and an empty monitor appears

Then, when I do:

i.pr.training map=liss.1@Portugal_9 vis_map=liss342@Portugal_9 training=outfile rows=3 cols=3 class=1

No image is displayed only 3 black panels and some instructions in lower-right panel. Instead of displaying vis_map. And, if I select randomly some points in the black space and save I get an empty file.

This image displays what is in the panel when I click on the panels (thanks to Joel Dinis)  http://yfrog.com/2mipr1p

Since i.pr.* is yet "just" an addon, I take liberty to downgrade the priority.
