>>If the class names have changed or the name of the classlib has changed then you have a headache of repointing the classes to new ones.

That would work, but not for the contained objects. In other words, say, you have a form with several objects. You can redefine the form, but you can not redefine the objects.

BTW, may be this is fixed in Andrus Moore's ClassBrowserX? I haven't treid this project.
