question re lock screen

[William Prothero]

I’m working on a transition from one stack to another, and initializing to destination stack’s screen before I show it.
So, my question is whether the lock screen command actually works on the invisible destination screen. Or does it only apply to a screen that is visible. How does it determine which “screen” to lock?

I see in the dictionary that lock screen does not work in the debug mode. Hmm…. makes it harder to debug.

Thanks for any info,
Bill
