Hi Paul, as I have been seeing strange things happening (also reported in this mailing list) I decided to remove all the programs and re-install everything from scratch. I am right now downloading: ifeffit-1.2.5a_Mac10.3.dmg horae-036.tar.gz Tk-800.024.tar.gz (I have read on Bruce's site that the newest version 025 is not good, but I wonder...) I have removed the /Applications/Ifeffit directory I have removed the /Library/Perl directory I have the latest version of fink, updated, in the /sw directory could you guide me into the exact installation procedure step by step???
