Apps won't update w/i OS X
iTunes tells me it needs a new version. It takes me to App Store. After FOREVER, App Store lists 6 apps that need to be updated. iTunes isn't one of them. And unlike usually, it doesn't give me an "Update All" option. It just lists the 6 with the update button to the right. But when I click on the update button, nothing happens with any of them.
Help? Any
Mac Pro, OS X Mountain Lion (10.8.2)
