Hi Gary,

Thanks again.

Strangely (or not) the class method cannot be overriden in the 
singleton. The argument about hacking the class method is somewhat 
buggered I believe (now). Since if B < A and I override the class method 
in B to return something else, it has no impact on what methods I can 
call on instances of B.
