1. Isn't it possible to isolate the line in Stack 1's handler where
this occurs and lock/unlock messages before/after that line?
on createStackForNetwork stack3CardId
copy card id stack3CardId of stack "Stack 3" to stack "Stack 2"
2. I'm still having trouble understanding why you can't predict when
and what will happen if Stacks 1, 2, & 3 are your creations. Only a
limited number of messages might trigger Stack 3 card handlers when the
card is copied to Stack 2: newCard, preOpenCard, openCard, and
closeCard. If you step through the handler in the debugger with the
Message Watcher open, you should be able to determine the line(s) that
trigger the problem.
