Mouse auto scrolling not available / working in Adobe Acrobat Reader

I simply want to click, then release the mouse wheel, and then be able to scroll up and down, say, a 60 page PDF document at the exact speed I wish, stopping and starting as I wish, simply by then moving the mouse on the mat forwards and backwards, no further button pressing or holding down of the button required. This is a standard, indispensably brilliant functionality I use on every single web page I visit, Word document or Email I read, it is only Adobe Acrobat Reader which does not have this basic mouse functionality, other PDF readers all have it as well, so why is it Adobe does not? I am aware of the auto scrolling option in Adobe which is incomparably inferior to the above method which is why everything has that really basic functionality I am talking about available as a standard function - everything except Adobe of course.
