knetworkmanager/kde4

[Paul]

I'm having a problem w/ knetworkmanager in kde4.  It runs as shown in a 
process table, but it doesn't appear in the system tray.  As a result I can't 
adjust any of my wireless connection settings.

Oddly, I have one machine running kde4 where it does appear in the tray and 
one where it does not.  Both machines also have a full kde3 installation 
although there are no logged in kde3 users.

How can I get access knetworkmanager.  Or is there a kde4 app which provides 
the same functionality?

Thanks,
Paul
