Microsoft retracts Patent

Anonymous Coward writes: "Here is something you don't see very often, if ever, and it was done by Microsoft, nonetheless: they have retracted a patent application. The story was first brought to light by Slashdot on Saturday. Today, Jane Prey of Microsoft announced on the SIGCSE (Special Interest in Computer Science Education) mailing list: "Many thanks to the members of the community that brought this to my attention — and here's the latest. The patent application was a mistake and one that should not have happened. To fix this, Microsoft will be removing the patent application. Our sincere apologies to Michael Kölling and the BlueJ community. Jane Prey.""
