NIS 2010 does not automatically display all available logins for a web page

I've just upgraded from NIS 2009 to NIS 2010 (version 17.1.0.19) and all went very smoothly.

However, I've noticed one difference with NIS 2010 and wondered if there was any way around it:

 

Whenever I went to a web page that required me to provide a login id and password, NIS 2009 would automatically bring up a window with all the available logins for that page (if there were more than one).  However, NIS 2010 does not do this - I have to click the "Cards & Log-ins" icon on the Norton Toolbar in IE8 and then click "Available Log-ins for this page".

Does anyone know if there is a way to force NIS 2010 to display all available log-ins for a web  page automatically (as NIS 2009 did)?

I am running Windows XP SP3 with Internet Explorer 8 (version 8.0.6001.18702).

Many thanks.
