Description

Handle the deleteButton message if you want to perform cleanup before a button is removed from the stack.

The actual deletion is not triggered by the deleteButton message, so trapping the message and not allowing it to pass does not prevent the button from being removed.

However, the undo command will restore a button after it is deleted by the user.
