Hi Alec
Thank you very much for your answer to my query. When I used Panel Write it worked. I passed on your advice to the music shop in Nelson and they also send their thanks. I did suggest to them earlier in the week that there must be a way that you could "save changes" but they didn't know how to do it.
What a great Forum this is - I puzzled away for ages and just over 2 hours after asking my question here, I receive an answer that makes it all clear. The helpful and friendly advice given on this Forum is very much appreciated. Thank you again Alec and to all others who so kindly share their knowledge and expertise with us.
