They can use their mouse to click the scroll bar between the "thumb" and the bottom of the scroll bar, but I am assuming that they want to use their mouse's scroll wheel?
That's pretty problematic. If I recall the details correctly, this can be made to happen if the layout is in list view and you limit the found set to the current record--but that may cause far more problems than it solves for many solutions.
Yes they would like to use their mouse's scroll wheel to view the bottom of the page.
I can't limit the found set as they are already working in a found set of around 20 and want to be able to scroll to the bottom of the page with the mouse's scroll wheel not between records with the scroll wheel. Is this possible?
