Well I just looked at installing Application filters then I get to the SDK examples - I've got to get out my C++ books and re-install visi C++ - not very likely I'm only just getting to grips with Java. So I presume there are lots of friendly people out there producing them to make a profit on - not stunningly impressed at this point in time. More of a whinge than a cry for help - where do I go from here assuming that I haven't got time to get the C++ books? Allan
