I am using adobe digital editions on windows surface pro. For my studies I am working with DRM protected books around 1000-1500 pages. Digital editions does not work fluently, with the touchpad its hardly possible to scroll, with an attached mouse, it is extremly slow. When I try to click on a button like the content, it opens seconds later. When I try to search a keyword, the programm crashes for up to 5 minutes.
What can I do?
There are lots of bugs in ADE2.0 (and 2.0.1). Try replacing ADE2.0 with the older but more reliable v1.7.2.
I don't know if it will help with very large books, but well worth a try.
You could also try Sony Reader; free download from Sony intended to run with Sony eReaders but works quite happily without. https://ebookstore.sony.com/download/
I prefer ADE1.7.2 to Sony Reader, but you may have different experience.
I think there is also an Overdr
(You can have them both installed at once if you like.)
Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.
The forum software is sometimes corrupting the link above. There shouldn't be a blank in 'editio ns.html'. The following redirects to the same page: http://tinyurl.com/diged172
Some people have found ADE trying to upgrade automatically.
It appears (not 100% sure) that if you install ADE2.0 as a new install (not as an upgrade) that your 1.7.2 will continue to run.
Probably best to say no if 2.0.x installation asks if you want to migrate your library.
