Just for the record, these problems were reported in: https://trac.osgeo.org/grass/ticket/2699 For list of active and closed tickets about g.gui.iclass see: https://trac.osgeo.org/grass/wiki/wxGUIDevelopment/wxIClass#Listoftickets > Thanks in advance for any help. > > Regards, > > Thayse Nery > > PhD.
