In adobe digital editions, "Page Dn" button does not take you to the lower half of page but it directly jumps to the next page.
If page is in "Page fit" mode then there is no issue but if you increase the font size it directly jumps to next page and not to the lower half of page.
I can scroll by mouse. And I don't want a resolution for myself.
I am just informing it so that you could rectify this in your programming.
