preOpenStack - Main stack script affects SubStack when it opens?

I think I've run into that and got round it by checking the name of  
"this stack" in the preOpenStack handler and only executing the rest  
of the script if I'm in the mainstack.  Actually, come to think about  
it, that was in a preOpenCard handler for a card in the main stack,  
not the main stack itself but I'm sure the same technique will work.
