When showing someone Squeak, one of the classic "wows" has been
rotating a window and showing that it still works -- and explaining
that there's not a line of code in the "application" code to make that
work, its gotten for free from Morphic.

Something since the release has it not work anymore.  It seems that a
drag-and-drop operation is invoked for a regular red click of a
rotated window.  It can be seen by attempting to click a class or
method on a rotated window..
