Hi all, I noticed that using the PTR-2 if you only have 1 book on a cd you can jump to page and the like. But if you have more than 1 book on the cd it does not let you use navigation is this correct and if so are the good folks at ptr-2 going to fix this in a future upgrade in firmware I use Dolphin producer to make my daisy books it works well enough all the best and thanks for any advice I am very new to this device and might just be doing something wrong.?
