Gang,
Any comments on the following?

I've consistently run into a problem when I copy something like a Button
object, which contains a cell of another class (Controls do this a lot).
The problem is that when the Button is copied, the ButtonCell that it
contains is not.  If I subsequently free the copied Button, I lose the
ButtonCell, and my initial Button dies if I try to use it.

Are ButtonCells supposed to be shared between buttons? (I doubt it,
since their "contents" field is really in the cell, not the Control).
If not, I presume this is a bug that should be fixed.

Thanks,
Dave  (combs@sumex-aim.stanford.edu)
