Question About PreOpenStack

[Mark Schonewille]

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.

The absence of OpenStack handlers appears to have been the problem because, after the the sub-stack executes its own PreOpenStack, the main stack, for whatever reason, executes its OpenStack.  This, of course, can be disastrous if the main stack is intended to initialize an app or perhaps contains sensitive material that should not be revisited!  My fix is to include an OpenStack handler with nothing in it in every sub-stack in order to trap the message.
