"Click with the mouse on the background of the main window to show the world menu, then choose Workspace to create a new workspace."
That's from "Pharo By Example." Only, if you download Pharo today, the above description (and the illustration in the book's text) don't match the way Pharo works. As far as I can tell, Workspace is now called "Playground."
This is the problem with projects like this; and, believe me, I have been at least somewhat interested in Smalltalk for years. When I download something and come across the above by Page 3 or so, I just expect a lot of extra little frustrations that I don't need, and that turns me off to the rest of it. Smalltalk is different enough to begin with. I don't need extra aggravation.
