GK, I'm glad you got it sorted and submitted - does that solve all your problems with the Grauniad, or just with the Genius?
What browser are you using, because I downloaded and installed the latest java yesterday (repeatedly with restarts etc) and firefox said it was there and up-to-date, but the Gdn page for the Genius wouldn't recognise it, and neither would another website.
I tried google chrome but it fell over when I got the home page of the Gdn up.
I have no idea why this is so useless, or why the Gdn's own link to the print version was wrong. I see you played 'good cop' with the Gdn in your email. I'm afraid I played 'bad cop' and told the crossword editor it wasn't good enough. I haven't had a reply, either!
Hope you win the £100.
