itunes freezes any time I add anything.
I'm running OS X 10.9.5 and iTunes 12.6.6.20 and have the latest "Updates" from the App Store. iTunes opens and functions flawlessly until I add music to it. Then it freezes. I cannot scroll through anything in the left column AT ALL! To quit, I have to go to the iTunes in the Dock and right-click: QUIT.
When I relaunch, it's fine again until I add anything.
Tired of this!
