Scrolling within re-sizeable windows
Both ModernMix and RetroUI Pro can show scrollbars on the re-sizeable window of an app whenever there’s more of an app’s layout to see. You can also use the arrow keys, and Page-Up and Page-Down keys on your computer’s keyboard, as well as the scroll wheel of a mouse, to see any other areas of an app that are out of frame. Some apps I tested would not display scrollbars, whether I used either program. For example, the Windows 8/8.1 default Weather app wouldn’t show a vertical scrollbar when it was obvious there was more information to be viewed. Any scrollbars that appear are apparently a UI element originally written into the app itself -- they are not elements overlaid by ModernMix nor RetroUI Pro.
