Hello!
I use calibre extensively to manage my ebook library. I store all books in both epub & mobi format, as I use both a Kindle & Nook.
All my books start as epubs, then I convert to mobi using calibre. Usually with default conversion settings, as I get the epubs how I want them before I convert (with Sigil).
The built-in calibre reader displays the epubs perfectly. However, when I use calibre's built-in reader to read a mobi, the book appears to have lost it's formatting somehow. Pages are all blended together, there is no separation between the table of contents and the beginning of the story, text has been resized in certain areas, etc... just all kinds of problems.
Now, when I view that same book on the Kindle device, it displays just fine. No errors. Same when I view it on the Kindle for pc app.
So, I guess I'm asking if there's any known reason for calibre's reader to display the mobis in such a way when they appear differently in the Kindle reader.
Below, the image on the left is the (correctly displayed) epub; the image on the right is the mobi.
Thanks in advance.
