Hi Bob,
The object isn't a real object until the init is done.
Create a prg named test. In it put:
DEFINE CLASS test as Custom
PROCEDURE Init
? TYPE("o")
ENDPROC
ENDDEFINE

Now do
o=NEWOBJECT("test", "test.PRG")
o is undefined.

I cheat like this.
PROCEDURE Init
PUBLIC ThisApp
ThisApp = This
ENDPROC

Now ThisApp.Release can work.
