I have two Win7 computers, same version of IE, but this one runs Norton Internet Security and it will not keep me logged in on sites.  I'll go to a site, put my user name and password in, check "remember me" and the next time I start my computer, I have to log in all over again.  IE has not been modified, it has the same settings as the non-NIS computer.  Is there a way to stop Norton Internet Security 2012 from doing anything to cookies?
