Yahoo Flickr Sign In Problem

[Dajstar]

I cannot access my flickr account , when the yahoo sign in page comes on, it auto fills username and password as normal , but the sign in button will not activate ... so nothing happens.
Contacted yahoo and they tell you to disable any anit virus firewall etc that could conflict it but still not work.
Never had a problem before but now cannot get on at all.

Any ideas ??

Thanks in advance.
