I am running OS X 10.4.11 on a "pod" iMAC. When I open system preferences and click on network, I get a pop up window that states my network preferences have been changed by another application. When I click on the green "OK" box the pop up goes away and comes right back. This is driving me crazy because when it gets into this cycle it's almost impossible to get out of the preferences panel or even check the settings! It's like it gets into a closed loop and won't let you do anything. Any ideas on what I might do to stop this pop up???
