Strange thing has been happening since, I believe last Patch Tuesday (6/09). Context menus and message boxes don't stay "focused" (on top) if I move the cursor out of the window. Can hover/click on taskbar icon to get back on screen, but as soon as I move the cursor, it's gone! Doesn't happen with snapped windows or app windows, just context menus and message boxes and the like. It's happening on Win 10 and my dual boot 8.1. Also, on my laptop 8.1. Only thing in common, they all had Flash Player update. Anybody else getting this? Any clues?
