Using 'Edit Metadata' in Calibre, I downloaded the metadata and an Amazon cover for a book that had been converted to mobi format. The Amazon book cover now appears in the 'Edit Metadata' screen. I then clicked on 'OK', and the Amazon cover now also appears in the main Calibre screen.

1) when I open the cover.jpg file, it's the Amazon cover
2) when I open the book in the Calibre E-book Viewer, I still get the original generic cover
3) when I open it in Kindle for PC viewer, I still get the original generic cover
4) when I view my Kindle for PC library, the Amazon cover appears there
5) when I email both the mobi and the cover.jpg file to the documents folder of my Kindle Fire, I still get the generic cover, both in the folder and in the viewer

How might I get the correct cover to appear in the Caliber viewer, the Kindle for PC viewer, and the Kindle Fire folder and viewer? Any assistance would be much appreciated. Thanks.
