problem with Gorm

[nyap hong]

I have a problem that related to Gorm. 

I tried to created a simple GNUstep-based program
using ProjectCenter and Gorm. I followed every single
step written in 'GNUstep development tools : a basic
tutorial'. I wanted to create a new class. According
to this tutorial, select the NSObject class in the
main window and then click on Classes->Create Subclass
in order to create a new class the extends the root
class. After that I should see an inspector window
that named Custom Class Inspector, but what I get is
GormClassProxy Inspector which does not allow me to
change any properties and attributes of the new class
that I have created. 

Is there anything wrong with my Gorm program and how
to solve this problem?  My Gorm version is 0.2.0.
