It’s a beta, Apple Store isn’t going to help. File a bug, as Apple is famous for their timely bug feedback and fixes (that would be a strongly sarcastic statement, for those that have not dealt with Radar).

I'm aware of the beta trap.. and I'm waiting for the final release to come out to see what happens, but given that we're on the 2nd RC, I'm willing to bet all my money that the bug persists.
