Thinkpad Trackpoint Centre Button Doesn't Scroll

When working in most programs, such as MSWord, on a Lenovo Thinkpad, when the centre Trackpoint Button is held down at the same time that the centre keyboard toggle is pressed up and down, it possible to scroll up and down the page that is being viewed. This doesn’t happen in Scrivener, and the inability to use this feature to scroll is inconvenient. I hope this is corrected as the software continues to be developed.
