My comment wrapped. Sorry.

Hi Graham,
What happens if you do only this?
lock messages -- assuming you don't want any handlers to be
triggered by the stack's closing
delete stack "myDataStack"
I'm also assuming "myDataStack" is a mainStack and not a substack. (As
you know, you can't remove a substack from memory independent of its
mainStack unless you end its existence with "delete stack".)
Food for thought...

I have a situation where I want to close a stack and then delete it,
so that it no longer exists in memory and so that no naming
conflicts occur when I load a fresh stack with the same name. This
used to work - part of a script running in a different stack to the
one being deleted:
set the cantDelete of stack "myDataStack" to false
set the destroyStack of stack "myDataStack" to true
set the destroyWindow of stack "myDataStack" to true
close stack "myDataStack" -- this should ensure that there are no
messages operating in that stack
delete stack "myDataStack" -- this should remove it from memory
What happens in 8.1.1 rc2 (on a Mac with El Capitan, if that’s
relevant) is that all goes well until the ‘delete’ command, when I
get error 347, which is “stack locked, or object’s script executing”.
Well, since the stack is closed (this is apparent on the screen), its
scripts can’t be running, and it’s not locked (whatever that means -
the dictionary is not helpful), I don’t think the error is the
correct one.
The problem exists both in the IDE and in the standalone version of
the program.
I have two problems tracking this down:
(a) it used to work up to LC7.x; and
(b) an attempt to abstract the issue by repeating it with some very
simple stacks doesn’t demonstrate the error.
Can anyone suggest an approach to debugging this? I am totally foxed.
TIA
Graham
