Hi to all, I'm a new ifeffit user (I started using this software in october '03). My environment: Linux Debian/GNU, perl 5.008003, Tk 800.024 and Ifeffit 1.2.5 First of all, I would like to express my congratulations to the authors and thanks them all for their work. I updated the new versions last week and I appreciate the new more user friendly layout. But I found some strange behaviour with Artemis. 1. When Artemis starts, I receive this message: Use of uninitialized value in join or string at /usr/local/bin/artemis line 1236 2. Sometimes I save a project and when I reopen it doesn't found the datafiles (obviously I didn't modify the file names). 3. Sometimes the fit have no-sense values so I have to save the project, rerun Artemis, and with the same parameters I obtain good fit. It seems like after a certain number of fits the software starts to fail. I would like to know if someone have noticed the same behaviour. The problem is that points 2,3 are random. Thanks, Mauro
