I regularly upload Les Echos (French biz newspaper) on their website (http://www.lesechos.fr/pdf.php/20150413_LEC.pdf). After reading about 25-30 pages, the document closes itself, without prior notice and without saving any comments you may have made in the document.
This problem first occurred early February, when Les Echos decided to produce "lighter" pdf newspapers and it has happened on every single issue since then. Never before.
I contacted Les Echos to see if they could fix the problem. They answered that it was an Adobe problem.
So, my question remains the same: can you (or anyone else) fix that?
Thanks for your help.
