Hi again,
Being a glutton for punishment, I gave it another go, this time reading the instructions properly and getting a fresh install with no bookmarks, etc. I input the required address and got exactly the same issue.
Talking of issues, I get odd graphics issues with Windows 10, eg missing links until I run the mouse over their locations. I'm waiting for feedback from the W10 forum. Perhaps that'll help. I really don't want to waste any more time (or yours!). Thanks for trying.
