Identity safe blindly fills up values/ cannot select non identity fields

I am ready to give up on identity safe and Norton.  I have several sites where I log in with a user ID and password.  Once I get to the site, I may need to put in other information like for example a record locator number, my e-mail address or some other additional detail.  Norton automatically fills in the user ID/password and even submits it in those fields when the question is asked.  This often leads to getting logged out or not be able to submit the details.  If I turn off the auto-fill feature, then I have to manually enter the user ID and password, which defeats the entire purpose.   How do I selectively enable when it should fill, or when I do not need it to fill the details or once filled not to fill again for that session.   This is getting very annoying as I find many sites that need additional details like name of 4th grade math teacher -:) and I have to turn off Norton auto fill feature and then remember to turn it on again.  Even simple data like a record locator number is filled in by Identity safe. All questions that need to be filled are not user ID and password.  I would need to look at other products if this is not going to work.
