+1 Is the same as Michael wrote. [off] Tony, You need to be careful when you use Interfaces and constructions like above. Using constructions like that, you always need to remember: "Now I need a local variable to the compiler do the refcount..." "Here isn't necessary, because the argument is an interface type variable..." ...and so on. For this "problem" I have my own pattern. I wrote about it here http://objectpascalprogramming.com/posts/interfaces-e-o-metodo-estatico-new/ I write in Portuguese, but you can translate easily.
