I'm rewriting my script editor to use multiple cards in a single

When I first set this up, I had the stack's closeStack handler
delete every card from #2 on:
go cd 1
repeat with i = 2 to the number of cds
delete cd 2
end repeat
Why not use "for i = the number of cds down to 2"? Seems cleaner to
me. Though I know that the representation of cards in memory probably
has nothing to do with card order, it feels to me that peeling them
off the back would be cleaner than pulling them out of the middle.
And, as is most likely, the cards were not shuffled after they were
created, or inserted into the middle of the stack, it might actually
be relevant to the crash. I admit that's a stretch, though.
It may be a long shot, but if it helps pin it down it's worth trying.
Thanks for the suggestion.
If it's related to the crash, however, it may raise a question about the
stability of reordering cards.
We'll see....
I just tried the change to delete cards off the back on closeStack
rather than "delete cd 2" - still crashed. Once I removed that from
closeStack and reinstated it in the preOpenStack handler it resumed
reliable operation.
I guess the good news there is that reordering cards on the fly doesn't
seem to have a problem. :)
