Q: After I login, it takes me to the same page, what is going on?

A: Bugzero uses session to store temporary data, you need enable 
   'Allow per-session cookies (not stored)' for Bugzero to work.

     For IE5, the Cookies section is under 
            Tools menu - Internet Options - Security - Custom Level.
     For IE6, it is under 
            Tools menu - Internet Options - Privacy
     For Netscape, it is under
            Edit - Preferences - Advanced
     For Mozilla, it is under
            Edit - Preferences - Privacy & Security - Cookies

   Note that, for later versions of Bugzero, it should explicitly inform you so.
