Nice pick up. Now in Settings (in a fresh 60473 image), filtering on "halo" shows only: * Cycle both directions * Encloses fullbounds * Exhibits bounds so the comment seems irrelevant and #halosEnabled & #halosEnabled: each have one implementor class-side of Morph with one sender from MorphTest each, and one sender from Morph>>addHalo: and "Morph halosEnabled" ==> true, so the statement seems unnecessary. Would you like to contribute a pull request removing it? https://github.com/SquareBracketAssociates/UpdatedPharoByExample/blob/master/Morphic/Morphic.pier > Did you guys forget and leave out a chunk of the book? Its an evolutionary book originally from Squeak. It could well be that some parts of the book have been cleaned better than others to match Image changes. Thanks for reporting, and even better if you can correct it. cheers -ben
