I'm not sure this is the correct thread for this posting but I can't work out how to start a new thread

.
I have downloaded a copy of a non-fiction book to my PB360 in ePub format but it has a very strange way of dealing with footnotes and their superscript notations in the body text.
Is there a better way of making footnotes appear as they would in the hard copy of the book - say by changing the format?
Cheers,
Mike
