Note however that the first example used in the method comment, which displays a static label, does work. There is something wrong in the method of computing the changing label in the second example. I can't follow the code here, so I can't see the error, but it should be clear where to look.

Sorry even with that I do not see the 'Working on ' message.
It's just a progress bar with nothing else. No "Working on" anywhere.

It doesn't work anymore. (This worked in Pharo 1.4)
In the comment of Collection>>do:displayingProgress:
is a example, that doesn't work:
Smalltalk allClasses
            do:[:aClass| (Delay forMilliseconds: 1) wait]
            displayingProgress:[:aClass| 'Processing ', aClass name].

This should show the class names but it shows
only a single progressbar.
