You can use the following messages to capture the delete and prevent it from passing by checking if is one of the objects you wish to protect.

deleteKey
backspaceKey

--example
on deleteKey
   if "protect me" is in the short name of the selobj then
--do not delete
else
   pass deleteKey
end deleteKey
