Administrator with restricted rights, but with 'Manage status and Logs' access

Hello,

I upgraded the Symantec Messaging Gateway to version 10.6.2-3, and since then, an Administrator with restricted rights cannot work on the Management Web access. He can log in, he can see the Dashboard but not the graffics, and if he clicks anything inside the page, he is logged out.  

I tested the permissions in many ways, but when Manage Status and Logs is checked for view or Modify rights, we encounter these problems. When this access is not granted, everything is working as normal.

Internet Explorer version is 11, so is not the browser. Is this a bug?

Can anyone help me?
