Okay I think I see now why my closeStack handler never got triggered in the mainStack. The closeStack handler is in the card script! The current card of the mainstack is not in the message path. Interesting little quirk, but I see the advantages. The card script will only see closeStack messages for the stack it's in. The stack script will see ALL of them, including substack closeStack messages (if passed).
<sigh> My brain is not big enough to wrap itself around all the little idiosynchracies of LC. Not complaining, just saying.
