Ed,

OK - I'm an idiot! you CAN add an instance of an object with the same name as the class using the AddObject method. Sorry for posting incorrect information!

These objects need to share information between each other that could be obtained when they are initialized if it were done in the right order otherwise I have to finish initializing the objects in the Init method of the application class by calling a seperate method in each child object (.User.setUser(),.Version.setVersion()).
