I'm deriving a class from Form.

In my project i've designed 2 subclasses of this class (using the form designer as you would subclass the Form class).

In one form i'm trying to show the other one modelly, but i get the following error message: "Invisible or disabled control cannot be activated" when trying to either set the active control of the calling form to be the new form, or trying to set a control on my model form to be active.

Hope that made sense, any help would be much appreciated.
