So i've been working on this project for a few days. Today i'm working away and suddenly I noticed in the two main comp I've completely lost the ability to select anything in the comp window. I've attached a screen shot, you'll see how even though all the layers selected its not selecting in the image plane nor does anything highlight or select when I hover my mouse over it. If I select a layer and click and drag in the comp image plane, that corresponding image moves, however all other controls are missing. All other comps are working fine except the final render comp and the one under that.
I'm using a 27 inch imac with a second display. After Effects CC15.
Check the view menu. You have probably hidden layer controls.
Of course.... so simple. Thank you sir!
