Can't access the Library

If the Stacks Library disappears when you open the Info sidebar it’s because Stacks thinks the window is just too small to view them both at the same time. I’d recommend making your window much bigger – or if that’s impossible (like on a new MacBook or a MacBook Air) switching one sidebar or the other to the Window mode. That will give the other sidebar plenty of room. If neither works, send us an email over at http://yourhead.com/support and we’ll work through it with you. Isaiah

If not I would contact yourhead support.
