Here's another nuance on lock screen, throwing in preOpenCard processing just for good measure!
My preOpenCard code includes lock and unlock screen commands. While the screen is locked, I alter the stack's topLeft property, expecting that the user would see the stack in the location I set it to. However, the stack is initially displayed in one location then jumps to the location I set it to. My understanding of preOpenCard is that it happens before the stack is displayed so this behavior puzzles me. I had to move the code that adjusts the stack's topLeft into another handler and execute it via a "send in zero" command in order to get round some other issues with preOpenCard - could it be that delays the setting of topLeft long enough that it doesn't happen until after preOpenCard is done? This all with LC 5.5.0 and OS X 10.7.4.
