Covers not changing
This is my first post. I've been doing eBooks for a couple of years but new to Calibre!
Many of the books I have, have covers that I'd like to change. When I go to "Edit Meta Information" and assign a new cover, it shows up just fine. When I double click the book to view it in the little reader utility it shows the old cover.
How do I delete the old cover and insure that the new cover works?
