preOpenStack - Main stack script affects SubStack when it opens?

This is normal behaviour. The ways around it are...

1. an empty preopenstack handler in the substack
2. stack specific code in the main stack preopenstack handler

on preopenstack
   if the short name of me = [mainstack name] then
      do stuff
   end if
end preopenstack

3. move the preopenstack handler to the card script of the first card of the
main stack

Hopefully I've got that right.
