What version and build of InDesign? What operating system?
I'm on a MacBook Pro, 2.3 GHz Intel Core i7, 16 GB memory, OS X El Capitan, CC 184.108.40.206 InDesign 2015. I upgrade to El Capitain and CC at the same time. I had Maverick and CS6 before that. Maybe it is an OS issue but since I've upgraded both, CC Indesign and Photoshop are constantly giving me the spinning ball and crash a lot.
