I've attached a screenshot. Each drop-down-menu you see can received unintended selection changes during mouse-scroll navigation.

Since the scrollbar is so narrow, I use my mouse-scroll-wheel to achieve this scroll navigation. However, while scrolling with the intention of "navigation", if the mouse-cursor passes over the Output Device drop-down-menu, it inadvertently changes the drop-down's selection. The ability to change drop-down-menu selections, using the mouse- scroll-wheel is convenient in some cases, but it become problematic when the user is simply intending to do scroll navigation. I can see a non-advance user accidentally changing sound settings that they had no intention of changing in this design. Plus, even if they do notice the inadvertent changes, they might not know "what to change it back to". It may be better to disable scroll driven option selection changes in these menus.
