While Vivian was using my iBook tonight, she put it into sleep, and when she woke it up 3 hours later, she could not log out! The BBoD (beach ball of death) appears, and Finder just refuses to quit. Well. It is not the first time happening to me, but it is so annoying when the centrepiece of the operating system falls apart. The whole system just becomes irresponsive.
But luck the dock still works. So I started iTerm from the dock. Entered:
$ kill -9 -1
Bang! I am back to the login screen...
