Your thoughts on this are much appreciated. Darn right about the dangers!

Thanks Bob,
Another good tip to add to my notebook! Unintended re-initialization can bring
disastrous consequences. This, I have discovered. Sigh.

One of the things I do to prevent re-initialization of a card or stack is I
create a global, and upon successful initialization I set it to true. I check
it's value before initializing and only call the initialization handler if the
global is not set to true. This has the benefit of being able t
ges.

Good stuff. Thank you, Mark. I’ll give that a shot.

Hi Gregory,
Instead of putting an openStack handler in every substack, it is much easier to
move the openStack in your main stack from stack level to card level. If the
openStack handler is in a card script, it won't be triggered by opening a
substack.

Hi Mark and Jacqueline,
The substacks had PreOpenStack handlers that called a library stack and
sometimes emptied out some fields, but what they did not have OpenStack
handlers. The absence of OpenStack handlers appears to have been the problem
because, after the the sub-stack executes its own

There has been some good info about how to block a preOpenStack handler
from falling through to the mainstack, but I'm not sure that was the
question. Gregory will have to verify, but as I understood it, he has a
valid preOpenStack handler in a substack but it isn't executing.
Instead, he gets
Really?? I was under the impression that preOpenStack would not fire from the
first card because the stack was not open yet. You learn something new every
day!

The other way of handling this is to have a mainstack that is really just a
splash stack + library, it doesn't even have to show itself on startup (put "on
preopenstack; hide this stack; end preopenstack" into the script of card 1 of
the mainstack). Then put whatever you want for preopenstack be
I always put empty preopenstack, openstack, preopencard,
and opencard handlers for my substacks. I also put in a closestack handler
in the substack that tells the substack to close. This seems like it should
just be a standard thing to do when making substacks. This will prevent any
stray messages

Indeed, the documentation states that the preOpenStack message is

Messages from substacks auto
Hi Gregory,
That's called the message hierarchy. This is discussed in the user manual.
Messages go from front scripts to button/field to background, card, substack,
mainstack, stack in use to back scripts.
