Identity Safe, "Save Your Login" dialog not appearing for one website.

Recently I've been learning to use Identity Safe for efficiently logging into to various website accounts.  One particular account for which Identity Safe login has not been set yet I would want to include, but when I login to it, the "Save Your Login" dialog of Norton Identity Safe will not appear for me to store the new log-in.  I have had no trouble with several other new log-in setting of User ID + Password combinations, but the Identity Safe is not showing the new login saving screen for just one certain site.  I believe I can go into the Identity Safe settings and put in the login information manually, but should doing this really be necessary on some websites? 

 

Successes with sites: yahoo, aol, and an unnamed forum.

Unsuccessful (only in Save Your Login not appearing): gmx
