Took me half-a-dozen attempts and some ingenuity to find a workaround ....
The problem was that there is a banner advert spread on top of the 'User Name' box, obscuring it. So - no User Name entry, no log-on.
Stopping the page before the advert loaded was the only way I could find around the problem, then entering the User Name, then reloading, then entering the password.
Bit of a production ... would be useful if this could be sorted.
