Hmm! The world of 'puters!!
No, I have however had another 'issue' with HP printers where a lady I have set up with a domain address to handle stuff for a charity had some sort of 'upgrade' to an HP printer done by her son and it knocked out the Outlook email settings for the address (which had worked) and still worked on my Outlook. No network. Absolutely no way round it. Just about to delete the a/c settings and start again when it started up all on its own................
