While I was paddling around aimlessly, looking for the “default front page”, I stumbed across a memory test.
The images were: Knife, radishes, tree, dog, lamb, …
I clicked 3 or 4 objects, then all objects disappeared from the grey working area. The timer continued doing what timers do.
While I was assessing my emergency fallback, the objects re-appeared, but without the bowl of sheep’s droppings and the wolf. So I couldn’t complete the puzzle.
