I am having this and a menu issue in 4.12 and 4.13…
I cannot right-click on something and see a menu (title bar goes more gray but no menu)
No matter what I do I cannot create a new folder or copy/move something to a new folder, etc…
Same for the top menus as well…
Updated to latest nVidia driver 372.70, same thing…
Rolled back to the beta driver I was using, same thing… 4.11 and lower all work fine, but no dice in 4.12 and 4.13
I am using Windows 10 Dev Preview x64, have 3x GTX-980 in the machine, tried disabling GSYNC/SLI - no change…
Side-note, the editor windows is EXTREMELY BRIGHT on the ASUS ROG SWIFT PG2780 with 4.13…
(Like I can get a sun-tan from white backgrounds bright…)
