Is there any way to speed up scrolling in digital editions? My ebook textbook I bought for class is terribly slow just scrolling the page. Is there a way to speed it up or pre-cache or pre-process the file? This happens on both my dual core laptop and on my i7 8GB ram SDD HD-based desktop. Sort of inexcusable behavior from an ereader in 2013 that will make me boycott any future classes that require me to use this product to read content.
