macOS - FortiClient 6 : Shutdown menu item missing

I use FortiClient for VPN only. FortiClient 5 had a menu item "Shutdown FortiClient" that stopped both processes "FortiClient" and "FortiClientAgent". FortiClient 6 has only a "Quit" item which stops "FortiClient" but does not stop "FortiClientAgent". Am I missing something ? I stop "FortiClientAgent" using "Activity Monitor.app" but this is not quite confortable.

Under High Sierra, when starting FortiClient 6, all three items "VPN name/ User name/ Password" react very slowly as compared to FortiClient 5

Any comment ? All the best linus38
