I'm not sure that this article is very accurate. I recently read a book titled "Dealers of Lightning: Xerox PARC and the dawn of the computer age" that tries to provide a detailed history of PARC. In the book they say Xerox developed the BitBlt machine instruction that makes it possible to have overlapping windows. On this page they said that Xerox never developed overlapping windows. According to the book, Steve Jobs told the Xerox employees something along the lines of "Look, we've already go a bit-mapped display on our Lisa project but we think you have some technology that can teach us how to make the GUI easier to use." Which makes sense because the System's Lab of Xerox had what was called the "learning research group" that tried to see how children would respond to the GUI. I also seem to remember a qoute from an apple employee who said he kind of wished they never would have visited Xerox because it tainted everything they created from that point on. While they did use some of the Xerox ideas alot of the Lisa was original research according to that guy. Anyway, the book goes into a lot more detail and some of that page does agree with it.. just saying.. it doesn't seem entirely accurate.
