Correct grantalewis, there is no fix for this under 10.8.2.
The only solution at this point is to simply re-install 10.8.1, which for me meant installing 10.8 and running the 10.8.1 updater. Once you are on 10.8.1 do not update until after 10.8.3 comes out and we are sure this problem has been fixed.
What a joke! I doubt this guy tried his suggestions before writting this article, because none of them work.
