Isn't supposed to be a monitor display? i.class should bring up an interactive workspace in the Xmon with control buttons in along the bottom etc. screenshot here: http://bambi.otago.ac.nz/hamish/grass/screenshots/i.class_in_action.png resulting sig file (in $MAPSET/group/$GRP_NAME/subgroup/$SGRP_NAME/sig/ # #trial 496 when I exit the program it just says: ....
