Thanks again! I can now see how it all works, thanks to you! It was a bit over whelming yesterday as I had not upgraded my iMac to Lion ( i had it downloaded ready to install but was a bit twitchy about it) and I did it yesterday.
No problems, but then I had to install an upgrade to Lion and install OS5 on my iPad and then the new iPhone arrived and I was tired and not really sure of what I was doing!
Anyhow it is all fine now and I am very grateful that you took time to explain it to me!
Next time you come to the UK, I owe you a beer!
