Is it possible to start different mol-sessions from different config files. e. g. I have two config files with the names molrc.jaguar and molrc.panther and what i want to do is to start one sesion from the molrc.jaguar file and one from the molrc.panther file and run them simulotaniously. I have solved this now by using the altconfig in the molrc.osx file. /Erik Hedman
