Hi Bill,
To retrieve the icon, right click on a blank space on the Taskbar. In the
menu that appears, select 'Properties'. Next, select the 'Notification Area'
tab. Under the section headed 'System icons' there is a list of icons which
you can set to either always show (ticked box) or always hide (cleared box).
I recommend that you have all of these icons set to always show, i.e. have
the boxes ticked. The options that I have in this section are Clock, Volume
and Network. There is another option, Power, but that is only applicable to
laptops.
