#72 Error trying to save

[Carl Alphonce]

I am entering this bug on behalf of Mark Jensen, CSE115 UTA.
--------------------------------------------------------
Carl,
I captured the stack run when a student had this error. I was able to get rid of
the error. It occurred right after he deleted an import statement. He also had 2
green diagrams running, both open. By replacing the import statement, everything
was able to be saved and I could delete the extra diagram. I don't know if it is
related to what is actually causing the error.
