Poor argument, Nigel. If I buy Exhibit A, I own Exhibit A. Agreed?

If I then dispose of Exhibit A without having made a copy, where does that leave your point? Is it not OK to dispose of something you have bought? Of course, that's not what you are suggesting, but you see where this is going, yes?

Sorry Dave - mea culpa, mea culpa, mea maxima Mudcat meander, etc! ;-)
