I'm using the excellent solution from http://www.gamesas.com/index.php?/topic/1262967-keyboard-binding-fix/, and I've found that I pick up books by using "Activate". I also, however, can't drop anything, and thus must find a container, and I'm avoiding duel-wielding because I'm getting tired of problems and don't want to deal with another.
The "activate" button works for picking up everything else, but for books, it opens the reading layout view and then from there there is not any button I can press that allows me to take the book.
After playing for quite a long time, I discovered one more issue related to the UI/keybinding problem, which is quite severe.
It is not possible for me to unlock dragon shouts using dragon souls due to this same problem. The first three words were unlocked by the Greybeards; however, when I attempted to unlock a shout on my own for the first time, I experienced the same problem that does not allow me to drop inventory items or add books to my inventory.
The button that unlocks shouts is "R", which I have mapped to a key on my NumPad. That key doesn't work and neither does the "R" key on my keyboard, nor clicking on the option with the mouse. I also tried quitting, disconnecting the NumPad, reloading and pressing "R" on the keyboard, but that didn't work either.
The menu appears like this: http://cloud.steampowered.com/ugc/612716583482241705/363FF144032E915D0A43CA24CB3134E8EE00FA86/
No matter what I do, I get the following error message: http://cloud.steampowered.com/ugc/612716583482316919/440F70BE649E68AF5528AEC5A565C0A9BA82D300/
