I think it's likely that there is a bug in your code and you are using  
the same dictionary twice, since mutable copy works reliably for  
everyone else.  Alternatively, perhaps you are really saying that you  
want to make copies of the objects in a dictionary rather than a copy  
of the dictionary itsself.  If that's what you mean, then you probably  
want to use the -initWithDictionary:copyItems: method to initialise a  
new dictionary so that it contains copies of the objects in another  
dictionary.
