Query: Great content, few difficulties on kindle

Paul Ekman gives a very useful and comprehensive instruction on how to read emotions from facial expressions. I probably would have given five stars for the printed edition. But having downloaded it on my kindle I can't use chapter ten properly, where the reader is invited to cut out the pictures for practise. In my opinion that's a real disadvantage one should know before deciding which edition to buy.
