I have three different book readers: iReader (free), FBReader and finaly Aldiko Book Reader Premium (1.2.9). This reader works kind slow (in my opinion), but I can accept the speed if everything will work fine.When I'm trying to read those books are included with Aldiko everything is fine. When I'm converting my books using PC software - Calibre, the book created *.epub starts so long and screen become gray (dark gray)... and that's it. Nothing happens.The books are converted properly, because I've tested the same books with FBReader and everything is fine. Of course, I can use FBReader instead of Aldiko - but I would like to know why Aldiko cause this problem, anyone experience same before?
