Getting Python to show ATL & MFC Dialogs

[solid.snake.84 at hotmail.com]

In my ATL Class, I have a function with the body

STDMETHODIMP CSimpleObj::Show()
{
     AFX_MANAGE_STATE(AfxGetStaticModuleState())

     // TODO: Add your implementation code here
     CSimpleDialog myDialog;
     int result = myDialog.DoModal();
     MessageBox(NULL,TEXT("Live From Python"),
     TEXT("MFC ATL COM"), MB_OK);
     return S_OK;
}

and python script is very simple

from comtypes.client import  CreateObject
MFC = CreateObject("MFCATLCom.SimpleObj.1")
MFC.Show( )

if does return a success message, but niether the Dialog nor the
Message box appears. Does any one know what's going on?
