how to set network? where's nm-applet?

after booting into Bodhi moksa desktop,
there's only a quickstart guide telling me that
all I need to do is left-click on an nm-applet icon

but the problem is : there isn't such an icon there.

after some time, I found that if I logout ,
and then login again, using 'bodhi' and blank password,
then, this nm-applet icon appears, and it works.

or, without logout, it works if I execute command 'nm-applet' manually

why?

it's latest 5.0 and I tried in both vmware and laptop
