The documentation is busted. Here's a message from Corbin Dunn stating that they work without layers: http://www.cocoabuilder.com/archive/message/cocoa/2008/8/28/217039 And here's another one from Scott Anguish: http://www.cocoabuilder.com/archive/message/cocoa/2007/11/23/193766 The documentation is wrong, but what else is new?
