Here is a question that some of you may be able to answer. I was previously reading through a PDF file on Google Books on an old periodical that was printed in double columns. Previously, it had allowed me to copy and paste from one of the columns without slipping over into the other column. However, when I tried to do so recently, it started copying from both columns instead of the one which I wanted to copy the text. Does anyone here know how to fix this problem and just be able to copy from one column at a time?
