Why does Internet Explorer sometimes remember previous entries and sometimes not?

For example, login details. My friend and I login to the same website every day using the same login details. On her PC it remebers her login ID, on mine it doesn't.

On other sites, it does remember my login ID, so there must be a per-page setting somewhere.

What setting do I need to change?
