Finder windows jumping back behind other application windows
I'm experiencing a glitch in Finder that makes Finder windows jump back behind other application windows? It's driving me crazy.
When I use Mission Control or App Exposé to show all application windows, and then select any Finder window, it immediately drops back behind the other open application windows.
I'm using macOS Sierra (10.12.1) on a Macbook Pro, (Retina, mid-2012).
