A stack in RAM doesn't get the open* messages because, technically, it's
already open. If you set the destroystack property to true, then the
next time it opens the normal messages occur. But in this case that
would delete your temporary clone, so you can't do that.
You could specifically send the messages after you set up the properties:
-- set up the clone, then:
preOpenStack
openStack
or, depending on your stack organization, you might need to:
send "preOpenStack to me" , etc.
If you will be closing and reopening the stacks multiple times, you
might trap for "resumeStack" instead.
