You are correct. I messed up and was running 4.5.2 on the Mac. So,
what this means is that from 4.6 on backgroundBehavior = true for
groups on >1 card is the expected behavior? Anyone know why this
change was made? It seems like a pain in terms of message passing for
groups that are intended to act like self contained controls rather
than a shared resource on multiple cards.
