Dear Alex, Thanks for your help. I copied back over the gc.config file and put /opt/iona/etc explcitly in my library path (before it was being added to my path by the shell script -- which is why I could run the cmanager). Now everything seems to work fine. Thanks for your help, stephen -- Stephen C. Johnson Dept. of Physics and Astronomy The University at Stony Brook Stony Brook, NY 11794-3800
