Min browser 'Get' preceded by 'Get' sysObjectID

Min browser 'Get' preceded by 'Get' sysObjectID

Mib browser in SNMPv2 mode works OK.

In SNMPv3 mode every 'Get' is preceded by 'Get' sysObjectID.

Output below shows a 'Get nstAgentModuleObject' but is always preceded.by 'Get sysObjectID'.

Why is this happening?
