Definately a bug, definately not the desired behavior.  Yikes!

The only suggestions I can make for now are:

1. Run feff from within Artemis.  What you describe does not happen
   for me in that case.

2. Import all the paths and exclude or remove the ones you don't want.

or 3.  Use the preferences dialog to set the "paths -> firstn"
       variable to a sufficiently large number, then try starting the
       project again.


I acknowledge that these solutions have their shortcomings, but I
probably will not have time to fix this problem before I head to NSLS
next week.  It could be two or three weeks before I'll get around to
posting a solution.

Thanks for the bug report!
B.

P.S.  Is there a reason that running feff outside of artemis is
preferable?  I am not criticizing -- I am just interested to know how
people are using this stuff so that Artemis can better serve your
needs.
