Publish and Subscribe works differently in ClarisWorks and ClarisImpact than it does in MacDraw Pro.
All of these programs allow you to select any object or objects from a document and publish them. However, ClarisWorks and ClarisImpact publish everything inside the rectangular Publisher boundaries. MacDraw Pro works differently in that it only publishes the selected items regardless of the proximity of other objects in the document.
Therefore, anything that is close enough to the selected objects to fall within the boundaries of the Publisher will be included in the edition file.
