Like everyone on the Mac, I got that dumb java error when trying to run 2.7.

I ocassionally program in java and that is a very basic problem. Not finding the MAIN class??? My god that is like JAVA 101. I'm surprised that it passed any kind of testing or QA or that it takes more than 2 seconds to fix. Oh well.

Go back and install 2.6 which works.
