tbh I'm not sure that would resolve the problem if your IP address was still the same, and we know that changing the IP address can work when there are access problems. I'm sure I sent an email a few weeks back for you to pass to your IT guy setting out how you could try this.
I'll check and will re-send the e-mail.
Yes, you did send an e-mail, Gordon, thank you, and yes, Ian did see it. The problem seems to be to do with SuperNova because dolphin do not work with other IPs. They are working on it, but it might take a few years yet before they have cracked that one!
Apologies if I did not send a reply.
P.S. re-sent e-mail arrived - thank you.
