I did get errors Mark - see below.
To add to the fun, my internet connection keeps dropping out then coming back. I assume either BT or my ISP is working on it as I type, since the router seems to be quite happy and claims to be connected. I re-booted it to be on the safe side. Maybe the drop-outs explain some of the problems below (I'm thinking of the last five lines in particular)?
Thanks for your help, as always. Forgive me if I don't respond tonight. I may not be able to..
