I've been monitoring cnn.com/live for a few weeks. Until a couple of weeks ago, no problem. Now I can get audio only - no video. No problem anywhere else -- YouTube comes in just fine, for example. Checked with Apple Care, and it's not my Mac. I am strictly an applications jockey - no "under the hood" troubleshooting skills here. Anyone got help on "Fully Functional Flash on MacBooks for Dummies"??? Thanks!
