Thanks for the replies.

@robko:
I just tried opening a book which had no problems and a book with problems, simultaneously on Calibre. The same situation was there too. So I don't think this is necessarily a problem with the Mini. I also tried converting them to .epub (they were .epubs to start with anyway) and that didn't help.

@GeoffR:
I haven't converted this myself. I am not sure if the original file was a .pdf either.

I believe the problem is that the readers can't determine where to hyphenate words. As such, when they meet a long enough word which wouldn't fit on that line without hyphenating, they simply jump to the next line. Nobody else has this problem?
