As a complete newcomer to C3PO development, I got the C3PO developers kit,
and tried using the C++ sample code (C3POByWiz). It all compiles OK
(using Visual Studio 6.0), and the DLL appears to register OK. The
registry entries look OK (according to the documentation), but the menu
entry which should be created isn't visible in the GW client. Adding a
MessageBox call to the C3PO Server 'Init' method indicates that the DLL
isn't being loaded (ie. no message popup)

I only have GroupWise client 7.0 so I can't try it against any other

What am I doing wrong?
