iTunes can’t be hidden with option-click
I just noticed something odd: I frequently push applications invisible to the background by option clicking on the desktop or another app. That will activate the app you clicked in and hide all the current app’s windows.
For some reason this does not work anymore for iTunes. It just deactivates it’s window and switches to the other app.
Hmm. Command-H (Hide iTunes) also does not seem to work. Lame. They were probably too busy porting the iTMS to the iPhone.
