Dear Earnie,
Thanks very much - I greatly appreciate your help. In fact it was a mysterious .htaccess problem, which I circumvented by going in to the admin section manually via the address bar, as though clean urls weren't specified. I am currently doing a much needed update to newer versions of core and modules.
Thanks again, and all the best,
You might want to visit http://www.for-my-kids.com/Upgrading-Drupal to see the steps I took upgrading a site from 4.7.3 to 6.10.
