Dear Bruce and dear mailing list, Athena stops working after doing a maximum of four steps (f.e. removing points, import data,...) when running on my PC with Windows 8. It either says "not responding" or just shuts down. Whenever Athena shuts down the errors in the .txt in the directory of the project differs. But it always looks like this: line 0: warning: Skipping unreadable file "C:\Users\Michael\AppData\Roaming\demeter\stash\gp_leqfnhqh" line 0: No data in plot only the file name changes. But there's never a file with that name in that directory. Sometimes there is as well a window opened that says: gnuplot.exe is not working anymore. I've deleted the Roaming\demeter folder but it didn't end the troubles. Hope there is a way to end this problem. Sincerely yours Michael Koemm PS: There is also one of my projects in the attachment.
