Just a quick note about loading WithStyle. WithStyle relies on a reasonably new version of Pollock and depending on your version of VisualWorks, you may not have a new enough version.

I include in the .zip file a copy of Pollock, System-Announcements and Model-Observables that are compatible with WithStyle. Note, though, that if you try to load the WithStyle bundle, VW will not use the copies of these parcels in the '.' directory, but instead will use its own copy. So - you have to load System-Announcements, then Model-Observables, then Pollock - and only then can you load WithStyle.

Eventually, a standard Pollock will be enough and I won't need to zip up a compatible version - but for now, you need to follow this procedure.
