Missing glow behind the titles of ribbon-enabled windows such as File Explorer and Wordpad, is well-known. Those window elements are composited from resources from some other place than those managed by Aero Glass for Win 8.1, and a theme replacement needs to be done to affect those particular titles. I've come to just ignore it myself, rather than delve into theme replacement. Managing themes is outside the realm of Aero Glass for Win 8.1, though BigMuscle did at one time offer a tool that will relax the security requirements of Windows 8 and facilitate loading of themes. But again, that's separate from Aero Glass, and unfortunately I've lost track of the URL from which to download it. Maybe someone else remembers it. -Noel hmm, okey
