Re: Strange Behaviour: CellAutoOverwrite

If it only happens in this notebook, then it almost certainly is an option which 
is set at the notebook level.  You should, in the notebook, evaluate:

Options[EvaluationNotebook[]]

Perhaps something will be obvious.  If not, feel free to send either the output 
of this command or, somewhat preferably, the entire notebook my way and I'll
check into it.

Sincerely,
