Ok i'm a complete newbie to the forum but i've been using Calibre forever... I've never really had any problems i couldn't look up but i can't seem to figure this one out.
When i've converted just 2 certian books from .lit format to .mobi so i can read it on my kindle, a lot of the words have dashes insterted between them. It's readable but complete annoying when trying to read.
I've converted pleanty of other books from .lit format and never have this issue. I just use the defualt settings when i convert.
Can someone help me out?
Thanks!
