Subject: [IronPython] Running applications vs. forms?

To clarify my earlier message-

If I want to create a non-trivial application, I will have several forms and dialogs. My(apparently broken) understanding is that I would create a class representing the application and pass that to the Application.Run(method).  For example, the tiny app here:


import clr
clr.AddReference('System.Windows.Forms')
clr.AddReference('System.Drawing')

from System.Windows.Forms import Form,Application

class Form1(Form):
    pass
class Form2(Form):
    pass
class MyApp(Application):
    pass
a = MyApp()
Application.Run(a)


Produces 'TypeError: cannot derive from sealed or value types'. Alternatively, If I create a class with no inheritance, I get 'TypeError: bad args for method'. What is the correct way to do this?
