network button on configure shelf doesn't work

I originally setyp my network parameters (DHCP, etc) using the
network button on the congifuration shelf in photon

QNX rtp, 6.1A

Now, pushing the button doesn’t bring up any dialog boxe on the screen
as it used to. Button push “appears” to have no effect

I created a terminal window and did “ps” from the command line, and I
see a whole bunch of entries for both ‘netmanager’ and ‘phlip’, which
indicates that either the process is:
hanging, and each time I try another pair of processes hangs
the window is somehow there but not visible

Any ideas? The network is working (ping works and voyager works) and
I checked in WorldView to be sure that the network window is not
showing up in another pane
