Ben,

I took a look at this and Metacell has wrapped the load expressions with a MetacelloPlatform>>do:displaying: call that presumably is supposed to show the progress bars continuously during a Metacello load, but a check in Pharo3.0 shows that the Pharo platform class don't override the default implementation.

The original implementation of the method was in the Metacello-Platform,pharo package ... which was for Pharo1.0 --- so Metacello progress bar display has not been properly functioning since then (about 5 years) --- and not noticed until now:)

It should be possible to implement that method for Pharo6.0/7.0 and see continuous progress bars again ...

I would guess the problem with doing this pervasively is (IIUC) that Configurations are self-contained/self-bootstrapping so each Configurationhas its own copy of #load (I've no access to an Image to check right now)
Perhaps it could be a use case for metalinks.�� When Configurations are loaded, insert a #notify: at the end of certain api methods.

cheers -ben
