Manage Logins

I am running Windows 7 and NIS version 17.7.0.12.  I have previously used Manage Logins to automatically fill in logins to sites.  This function has suddenly stopped working (no fillins).  Identity Safe is turned on, Auto Fill when I visit this page is checked, and Enable Login to be auto submitted.   I see the list of websites for which I have logins saved, but no logins are filled in and I'm never asked whether to save logins for new sites.   Can anyone help on this?
