Dear Grass list I updated Redhat to version 7.0 and after that TCLTKGRASS did not work. The reason seems to be, that RH7.0 has tcl8.3 and so initscript tcltkgrass does not load proper tcltk version. Would somebody show me please, how should I update my tcltkgrass init. Many thanks beforehand. Best Regards Seppo Kaitala
