Restore iTunes 10 window controls
Fire up the Terminal and type this:
defaults write com.apple.iTunes full-window -1
I'm on tethered internet so I can't (and don't feel compelled) to download iTunes 10, so I can't check if this works or not. If it makes your Mac explode, don't come to me for a replacement. I would replace it for you, but I've got a lot to do right now you see.
