Not related to your problem, but important nevertheless: you don't need to free interface variables. They are reference counted an freed automatically at least if you don't mix a class reference (in your case to t_foo_base) and interface reference (in your case i_foo) which you shouldn't do anyway (and which you aren't doing in your example). I haven't work with delegation much, but you could try to do "(fc as i_foo).foo;". Also you might want to take a look at TAggregatedObject. Regards, Sven
