Hello DK,
I’ve got both named as 127.0.0.1, and it all seems to work OK (I’ll try your names and see if it makes any difference). Thank you for your help.
Once I discovered that the Google Toolbar was switching Firefox to ‘Work Offline’ whenever there was no web/network connection, my other problems vanished.
It’s a bit tedious having to switch it back and reload the local pages, but at least I know what to do. I’ll look for a way to prevent Google Toolbar from doing this when I’ve a bit more time.
Regards, and Best Wishes for Christmas and the New Year (It’s very cold and we’ll have a White Christmas here).
