Hi Micheal, thanks for the script! One situation that happens often is when I copy one object, zoom on it, select it, do some manipulations and I find out later that my original object has been modified also. (it was still in the active selection set.)

I agree that it may interfere with some type of workflow and it is not easy to draw the line.
But I get the impression that making backup copies seems to be a situation of exception in the general job description of the copy command. :)

Regards,

Marc
