You're very welcome - it took the best part of a day and tearing my hair out and a lot of swearing to find a way round it... so glad it's helped other people though :)

Yep - it's been a bit of a nightmare :-( Glad you're sorted too. Will have to check privacy settings now. Very worrying when you don't know what you're accepting but just grateful it's gone away!

I've just managed to get out of it by clicking elsewhere on the page which seems to un-grey the accept button - had to do this several times until eventually it disappeared. Absolutely no idea what...

I've got exactly the same thing from a Windows update last night. Desperate for answers as can't do anything :-(
