If you had bothered to read all my posts properly you would note that I am perfectly aware of this. Selective quoting is all very well but I am guilty of abbreviating far too much and being too wooly in my terminology. However, given the phantoms that are being chased down here that can be forgiven. Actually I will strive to be a bit more precise in future - after all I can't very well criticise others if I am guilty of the same sin.
