Stefano, Matt, Yesterday I finally got around to installing 10.3 on my G4. I'll try to take a look at this odd atoms problem today. It seems that there is a simple work-around. If the problem involves running the subroutine that parses atoms, you can run atoms and feff outside of artemis then delete (or rename to something other than "atoms.inp") the atoms.inp file, then inport the feff calculation into Artemis. If an atoms.inp file is not found when you import the feff calculation, the atoms tab will remain deactivated and the (apparently) troublesome sub will not be called.
