Performance & battery · Why background work waits or pauses
Why did the Junk Yard stop catching what I copy?
Short answer: Minimum (core only) mode turns off Junk Yard capture and the side curtain. Choose Automatic or another mode in the Storage Profile's performance menu to bring it back; otherwise check the Junk Yard is switched on.
If you've chosen Minimum — core only, that's the reason: Minimum switches off the Junk Yard's clipboard capture and its side curtain along with the other non-essential services. Choose Automatic or another mode in the Storage Profile's performance menu and the Junk Yard comes back.
If you're not in Minimum, check that the Junk Yard itself is switched on in its settings, and see the Junk Yard manual for other causes.
