I like to read a book in one window and take notes in org-mode in another. I like to put a link to the book I'm reading in the note file so I can open it when I want to study again. Unfortunately, two things happen that are annoying. The link that I store always has some pdf junk at the end rather than a page number.

Example: file:~/Library/Written/Medicine/Harrisons_Principles_Of_Internal_Medicine_17Ed_18Ed_19Ed_By_Samerbo/Harrisons19Ed/Harrisons19Ed.pdf::%PDF-1.6^M%\342\343\317\323

Also, even though it used to open the links in the same frame, but new window, now the links always open the books in a new frame. Is this normal behavior?
