Nice one Wolfgang! McGrath, thanks for the advice, but in this case it won't be nessesary. I know the person who did this terrible thing, and they did it on my computer while I was out of the room!! It was all done in good humour, But I had to put a stop to it 'cos people where looking at me funny round our end! I wont mention any names, but the person responsible playes a nylon strung guitar & rides a mountain bike!
