I recently downloaded an album from the iTunes 7 music store. The associated interactive book would not play

After emailing the iTunes Customer Service folks, and trying their suggestion, the problem persisted.

I then did some hunting and pecking in the QuickTime System Preference and found a setting to Enable Flash. That did the trick. Now the interactive books play back correctly. Apple today posted an update to a Tech Info article on the subject which describes the problem I had in detail along with step by step solutions -- try this link for the article I'm sure it wasn't written just for or because of me; but the fix works and that's all that matters
