Additional Comments
Expander triangle

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

Comments:

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

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

on deleteField

beep

send "undo" to this card in 5 milliseconds

end deleteField
