[Ifeffit] Problem with Demeter 0.9.18 pluck tool

[Bruce Ravel]

Denis,

I have 13.04 on several of my machines at work and at home.  I do not
see the behavior you are describing.  Let me try installing 13.04
fresh on one of my computers and see if the same thing happens.  If
not, I'll figure out how to troubleshoot.
