My version of the Official Guide for GMAT 2017 Edition is painfully slow - whenever I enter a new page number, it takes about one full minute to load. I'm on a MacBook Pro running El Capitan. This is really irritating, since I paid for a useless book, and what's more irritating is that there's effectively no way to seek recompense other than this forum. At least Amazon will talk to you - should I just buy the Kindle version?
