Bruce: the problem is with Artemis and project files. Athena runs smoothly with both data and prj files, while Artemis is smooth with data (Aquaterm opening) but cannot open Aquaterm when I read in project files. Is this a better hint? I think the problem is the old one: Artemis managing zipping and unzipping project files, but I may be wrong.
