Thanks for the clarification.
I thought you were talking about the pref pane itself when you said "icon" (but I wondered if your son had figured out how to do something I've never heard of).
I'm not sure how "Displays" has gotten into this discussion, but I guess it's one of your other missing SP icons?
I'd still love to have been looking over your shoulder, and I'll never understand files disappearing spontaneously from...well, from anywhere.
At any rate, I'm happy both to have
tried to help and to hear that you're back up and running.
