Without having tried it, I think you're missing a #wait message in there:

elements := #('eins' 'zwei' 'drei' 'vier').

elements do: [ :element | (Delay forSeconds: 2) wait ].

displayingProgress: [ :element | 'Working on', element asString ].

Cheers,

Shouldn't it just open a progress bar and iterate through the elements
printing 'Working on...?
