--- Comment #7 from jpleonard12@gmail.com --- Confirming the problem still exists in Wine 7.13.
Currently the scroll bars in Office 2000 apps (PowerPoint, Word) have become non-functional in with Wine 7.13 (perhaps as vaguely suggested in Bug #53424), but dragging graphic elements in PowerPoint to the edge of the screen still initiates scroll behavior that is disjointed.
