Are you using the ‘spread sheet’ view of your list? If so, the very far right column (in the middle/main/large browser area) needs to be slightly beyond the right side of the area (below/behind the scroll bar area). If you move the far right edge of the last column beyond the right side then the scroll bar will functional normally (instead of like a touch screen).
You can also use keyboard shortcuts to quickly move through lists:
End (move immediately to the bottom of the list)
Home (move to top of list)
PgDN (quickly move down list)
PgUP (quickly move up list)
Arrows up and down on keyboard slowly move through lists.
