I am a new member. I have been using CoolReader for Mobi and Aldiko. I came here becuase of a problem I encountered. I was using Coolreader 3 to read a book and everything was fine. In fact this is the second book. When I attempted to start reading a book again that I was half way through I have a problem. When I click the book to open it, the reader closes. I have reloaded the reader and the book, but the problem still exists. I have opened it with a different reader, but I do not like it as well. Any thoughts?
