Rodderick, Unlock Wallet for POS - not necessarily to do. Stake works fine and without it

Thanks for the info. The previous version of the wallet gave a warning message that staking was suspended due to the wallet being locked. I just assumed when I saw the red lock onscreen it would act the same if not unlocked.
Which leads me to ask, and perhaps I'm being a little too obtuse, what does the Unlock Wallet for POS option if not unlock the wallet for staking?
