I've had similar issues just recently when trying to edit the Titles & Properties of Pages, one after the other. Every other click on Titles & Properties results in the Titles & Properties page not loading, but the Pages interface refreshes.
Also, a client just called to report a similar issue when trying to edit items in eCommerce>Products.
We are both using the same version of Chrome (50.0.2661.94), but I am on Mac, client is on PC.
Firefox does not have the issue, so I'm thinking a recent Chrome update has broken something.
