Hi there i'm using grass for cygwin version 6.1cvs from 13-02-2006. I'd like to extrude flat 2D vectors with v.extrude. It ends up with a segmentation fault. Any ideas? Same problem with Radim's QGIS/GRASS port. Thanks Stefan -- "Feel free" mit GMX FreeMail! Monat für Monat 10 FreeSMS inklusive! http://www.gmx.net
