New MAC OSX version

I've been using the new version since its release. I always play AI against AI. I've found that it works OK when run as the first program used following start-up, but if I launch it after doing something else, it loses the brief delay at the start of each play that allows you see the pre-snap sets -- it seems to run each play from just after the snap. It will drop this delay in the middle of some games, too, even it is the first program run. Also, the Chalkboard Editor shows a slightly different shade of green in the player box than on the field itself. Anyone else have this happen?
