When I go to System Prefs and choose Network, I immediately get a message saying, "Your network settings have been changed by another application" and an OK box. No matter how many times I click "OK," the message will immediately come up again, and I can't use System Preferences at all until I force quit it and then re-enter. Even then, any return to Network settings immediately produces the same situation - System Prefs that are locked into the "Your network settings have been changed..." message loop. There are NO other applications running except System Prefs, Firefox (however, message continues even after quitting Firefox) and of course Finder. Note: nothing changed after a Restart -- still getting the message immediately upon going to Sys Prefs/network.

I am still online and on the net, and Built-in Ethernet still changes my IP address to adjust (DHCP) for other computers coming onto the LAN to access the internet - but I can't use Network to alter or lock in any settings, or even to Renew DHCP Lease, except if I act in the brief moment before the message comes back up again. HELP!

Background: I had to activate Network Utility briefly today to help troubleshoot a connection to an internet DSL router, but (so far as I know) the only thing I did was to use it to for a moment to ping the router. For a brief moment, somehow, Console opened (I didn't choose to open it), and heaven help me if somehow any text was entered, but I don't think it was. I'm totally mystified, here!
