ID Safe Multiple logins not always shown

I've recently moved to a new computer running Windows 7 Home Premium.

I also have the latest version of NIS 2011.

Usualy, when I go to a website for which I have multiple logins set up (in Identity Safe), the Identity Safe icon on the Norton Toolbar automatically dsiplays a drop-down list of those logins for me to choose from.

However, with some websites (notably Hotmail), more often than not I just get a fleeting glance of that drop-down list before it disappears (after less than 1 second).

Does anybody else have this problem and, if so, is there a way to fix it?

Many thanks.
