Bruce,

There seems to be a work-around.  If, instead, you always explicitly
close a project before opening a new project, artemis seems to behave
correctly.

unplesantly, not with my G4. I simply, this time, opened artemis and open directly the ZnO2.apj project and got the following trap:

# Artemis 0.7.005
# This file created at 22:31:50 on 1 June, 2004
# using darwin, perl 5.008001, Tk 804.027, and Ifeffit 1.2.5
# Workspace: /Users/stefano/.horae/stash/artemis.project.1/



The following message was trapped by Artemis on a SIGWARN:

Artemis0.7.005warn/Users/stefano/.horae/stash/ARTEMIS.TRAPCODE(0x1e3eb60)/Users/stefano/.horae/stash/artemis.project.1/ at /Applications/Ifeffit/bin/artemis line 1562

End of trap file.

Still stuck...
