Okay, I know that when iTunes LPs and iTunes Extras first came out, iTunes could not play them full screen. I don't know when it happened, but I just noticed that I *CAN* play them full screen now. (Either by selecting "View" -> "Full Screen"; hitting Command-F, or clicking a new "Full screen" widget at the upper-right on the "title bar" for the LP/Extra within the content pane of iTunes.) But, strangely, this only appears on one of my computers, even though both are running the same version of OS X (10.6.2,) and the same version of iTunes (9.0.2.) Does anyone know the secret to enabling this? I have checked every single setting in iTunes, both menus and preferences, and they are all perfectly matched between the two computers.
