I've used once handy to read e-books and I've used some app called Aldiko, that was downloading e-books in MOBI format.
After buying Kindle I've copied them into it, but when I try to open it, the book is opened on the end (at about 98%) and I can't navigate to first site. Navigating to 'begin' moves me to that 98%...
So it seems that the MOBI document is in some way 'broken' so that Kindle can't read it correctly. Is it possible to 'fix' it? And what can cause such incompatibilites?
