Ever have a locked PDF and you need to extract text? If so, check out GSview.
Today I had about 200 pages of text that I quickly needed to extract, and it did the job wonderfully. (Of course, the formatting was jacked up, but in my case, that wasn't too much of a concern).
Friends don't let friends deal with locked PDFs!
UPDATE:
To use this, first install Ghostscript, then GSView. (If you are using Windows [32 bit, chances are all you've gotta do is install this then this.)
