i've seen this more than once in a macbook. After using a Macbook 2.16ghz intelcore2duo 3gb RAM with OS X 10.5.6 for a series of days without shutting it down, one day, the airport status icon is empty, just the fan like shape is left - but without any lines or shadows inside as you would expect in an on/off setting. Then when you click it, 3 lines show: kAirPortStatusOffKey kAirPortStatusOnKey kAirPortOpenNetworkPrefsKey No network connection too if I open a webpage (it was connected to the net all this time). The Spaces and Time Machine icons in that bar at the top also looks funny/different. To resolve this, I usually restart the Mac (if relog-in does not work). I find this weird as Macs don't usually need to restart to resolve software issues. What is this error? Google does not provide any search results. Who else has experienced this? How do we make sure this does not happen again? Help!
