Good news, indeed!

Actually, I think it's an l (lower-case letter ell) and neither
capital letter I or number 1.  Those three characters look remarkably
alike on my screen as I am typing this! ;-)

After I finally understood the problem, I started looking into my
scheme for recognizing problems with the feff run.  It occured to me
that, if the feff_executable variable is set incorrectly, nothing
would get written to the palette window.  This is a problem since my
error handling involved seeing the contant of the palette window.

This afternoon, I have been overhauling my mechanism for recognizing
problems with feff.  The next release of artemis should be able to
post a useful message in the palette identifying the probably cause of
a problem and offering a solution.  Specifically, the next version of
Artemis should recognize Dan's problem and offer a useful tidbit of
advice.


And I want to echo Dan's excellent piece of advice regarding the
"window behind".  This is the command window that usually stays closed
and on the task bar.  It's the other item on the task bar that is
labeled Artemis.  That is another place to look for hints about
misbehavior in Artemis.  Indeed, I will often ask to see the contents
of that window when tracking down some bugs.
