in my case search for
/usr/bin/browser
process with lowest PID
running
ps -a

started internet radio applet
and a number of processes
/usr/bin/osso-media-server
appeared

Try to run ps -a
with web browser off and on
to see a difference.

The same for internet radio player.

You can save ps -a listing to a file
ps -a > yourfilename.txt
than open it in editor or file viewer.

But please run CLI commands, as below
and send screenshots

In my case (Nokia 770)
I have installed bash shell 3.2
I can run bash from CLI

~ $ bash
bash-3.2$

bash-3.2$ shutdown 1 -h
( no need for sudo gainroot)

rebooted after 1 min (the above)

=======================================

$ sudo gainroot

/home/user # shutdown 1 -h

shutdown 1
shut down and reboot after 1 min
