A screen capture of what you are visually able to see in the Web browser GUI would be helpful for me to fully understand your issue. That said, if you are not able to see the entire MENU bar at the top of the browser screen as shown in the attached picture (Image 2), that would be a java issue. Sometimes upgrading java or re-installing Java will correct this behavior. This can be quickly verified by using a different computer to view Balance.
Seen in Image 2, is an example of a User login into a Balance web browser GUI using a Balance "USER" account. User accounts remove the Admin and Configuration tabs from the top menu shown in Image 2. thus preventing NON admin users from changing system settings or removing discovered inventory.
Lastly, try logging in as login: support password: netapp this is the admin level account for NetApp Global Support
