I have had been bitten by surprisingly few bugs in the latest version of artemis, but I thought I would pass along an observation of one that should be easy to confirm. I am doing multiple edge fits and have in the past imported new data by using the project data item in the file menu. Selecting this brings up a dialog which asks if the new (path) data should replace the old data or should it be new (e.g. a new feff calculation). It doesn't appear to make any difference which option is selected, it always replaces the existing data. I seem to remember that this used to work in earlier versions... In any case, a work around is just to use the open item under the file menu which then does generate a new feff calculation entry. Oh, one more thing, as I recall Calculation is misspelled in the theory menu (it hurts to look at it as I live in a land with a lot of broken English (Japan))! Paul
