Brian,
I just upgraded to version 12.1.6 MP3 (12.1.6608.6300) and im still having the same issue.
Im also noticing that if i try and access using the web console (logged in as a full admin) i get certificate errors for Home, Monitors, and reports but Policies, clients and Admin all pullup fine.
Weve had sep for about 8 years and to be honest this is the first time anyone has asked for access other than me. So i dont know if all of these features have never worked or this is just something buggy going on.
