This morning, IDEA 12 preview prompted me to install the build referenced in the subject as an update. I went ahead and let the update install. After installing the update, IDEA 12 preview locks up during start up. The only way to recover is to force quit IDEA. Attached to this is the About box for this build. Fortunately, I have the dmg for the previous build so I am going to go back to that.
