Can't access Norton Account through Norton 360

I am surprised to find that if I select "Access Norton Account" from the main Norton 360 panel, after opening the web page and firing up the "sign in" screen all I get is an endless show of dots circling.  This seems particularly odd as I can easily log in via the Norton Anti-Theft web page which confirms that I have a current 360 license.

 

Running Norton 360 V6.0.1.2. under Windows 7 Home Premium and Chrome (17.0.963.56 m).  Norton Tells me that I am fully up to date.

 

[Edit - seems it is just a Chrome issue as I can get in through the same web address using both IE and Firefox.  Still strange that it works with Chrome from the Norton Anti-Theft site.]

 

This is not a serious problem as I can access the account in other ways but this does seem odd.  Is anyone else having similar problems (I have tried searching this thread but not found anything)?
