This apparently is an issue that has existed for some time and has not been addressed.
Scrolling in List view works intermittently in Windows. There is no real pattern to this problem, but it can be duplicated easily. Sometimes the scroll wheel works as you hover your mouse over one area of the layout, while in other areas of the layout it simply does not work. Moving the mouse to the rightmost part of the layout and then scrolling with the wheel usually (if not always) works.
This seems to be a problem when multiple monitors are connected and FMP is not running on the primary display. Many of my clients run multiple displays and unfortunately the vast majority of my clients are running on the Windows platform.
Note that there are often other display anomalies (remnants of lines, shapes, etc) that show when scrolling through lists in FMP on Windows.
