As I continue to work with my documents, I notice that I have more success with PDF files with single columns of text. I more able to highlight only the words that I want in that setting. However, with two columns of text (as is the format for most scientific/medical journals) I have extraneous text being highlighted. I could touch one word and end up with the entire line or more highlighted.

I look forward to any fixes enTourage can come up with.
