Yes, this was done to force developers to create these objects on the heap, rather than on the stack. Creating these objects on the heap makes it easy for the class to be subclassed later, if you wish. If the class is later subclassed, then you can create new objects of the subclass just by changing the implementation of the “createNew()” function - and the rest of the existing code will still work. But if the objects were created on the stack, then it would not be possible for the class to be later subclassed. Ross Finlayson Live Networks, Inc. http://www.live555.com/
