Network Manager stops functioning (sort of)

HI All

I am a new OpenSUSE user still (month two!) and have noticed a strange thing happen to Network Manager occasionally:

It will sometimes change the tray icon from the icon indicating a wireless connection to the icon with the “NM” displayed. I can then try to open it, and it shows me no information, I cannot disconnect or connect to different netowrks, and I cannot log into my VPN.

However, the wireless is still working. I tried disabling and then re-enabling NetworkManager in Yast, but no luck - that didn’t help.

Can anyone shed light on what is going on?
Running opensuse 12.3 on my HP DM4t laptop

Thanks
Chris

As the network manager client is normaly run fom a desktop and as you, talking about an applet, confirm that you use a desktop, cann you please tell which desktop you use? KDE, Gnome, LXFCE, …

My apologies, I am running in KDE 4.10.2Best,Chris

When this happens, please open a terminal window, and do


sudo tail -40 /var/log/messages
dmesg | tail 

and post the output here, between CODE tags (the # in the editor)
