Hi James, Yes I did follow up Katrin's suggestion but found nothing that looked obviously wrong, and anyway I don't think there have been any configuration changes since well before the problem first showed up. Following another suggestion *we have cleared the browser caches on all our client machines and everything seems to be working again*. I have no idea why, and am not convinced that the problem isn't going to come back at some point. But all is well at the moment.
Which leads me to a question I've been meaning to ask for a while ... *does Koha use cookies?* My thanks to all who suggested solutions. Much appreciated!
