I like the FONT CHOICE, seems alright - though my very large Jung - Red Book pdf forces K3 to restart.
Other formats work too....I will try again just before work - I have another pdf Nietzsche And Economy which I will try again later. But I like it, though it does not like my Jung book which the K3 can read.
Though my Sony reader cannot read it, I had to convert it to text for my Sony READER to read it.
