I suppose that usage is safe, but in general it's dangerous to use an Obj-C object for the context, at least in GC apps. That's because context is a void* and therefore not __strong. What I do (based on a similar discussion on this list some time ago, is to declare globals like: uint8_t kContext1 = <helpful # for debugging>; then use &kContext1 as the context. -- ____________________________________________________________ Sean McBride, B.
