Hi !!! I find why MOL don't start in YDL 3.0.1. I take source mol-0.9.69-1a.src.rpm and mol-kmods-0.9.69-1.2.4.22.2d rebuild RPM's inside KERNEL 2.4.22-2f and install them - Now everything O'k IT's Fine MOL working!!! I think that this RPM's of MOL were build with another KERNEL. May it help someone Best regards Serguei KSD
