According to [Apple Insider](http://appleinsider.com/article.php?id=1162) Apple is working on an update to Mac OS X Tiger, version 10.4.2. Couldn’t come soon enough for me:
>The latest build continues to weigh in at approximately 60MB and is reported to have addressed annoying glitches that arise in Mac OS X 10.4.1 when a user switches AirPort locations, attempts to log into WPA networks, or wakes a machine from sleep after network locations have changed.
“Annoying glitches” is too kind. When the kids are home, keeping their Mac Mini running 10.4.1 online is practically a fulltime sport. The Airport card appears to have a mind of its own, switching and dropping networks at will.
