Additional Comments
Expander triangle

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

Comments:

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

However, the undo command will restore a graphic after it is deleted by the user. For example, the following handler, placed in a card or stack script, effectively prevents a graphic from being deleted by the user:

on deleteGraphic

beep

send "undo" to this card in 5 milliseconds

end deleteGraphic
