I have an object, call it myObject, with a descendant, call it
myChild.  Both support a method, call it MyMethod.  in myChild, I want
to call on MyMethod in myObject, so I write inherited::MyMethod(...)
and it works fine.  In myObject, I want MyMethod to call on itself
sometimes.  Since the MyMethod is sometimes called from myObject and
sometimes from myChild, I can't merely call "MyMethod" or
"this->MyMethod", because in the case of the myChild it will go back
to myChild::MyMethod rather than myObject::MyMethod, which is what I 
want.  So, following the (very sparse) documentation in the Think C
documentation, I call "myObject::MyMethod(...)".  The result?  The
compiler returns "invalid method call" (or something approximating
that msg).  HUNH?!! 

thanks in advance,
LP
