Eric Running Windows 7; Used X-Mouse Button Control to make the side mouse buttons control the volume and to my surprise a Win 8/10 style interface appears. Have I not noticed this in Win7 for all my years of its use or has something else brought this in? i.imgur.com/ns936u...

John Olinda Whoa, never saw that before. All my machines are Win10, so I can't verify that it's a universal thing.
