Aha ... I am so pleased it wasn't something really dumb and obvious, I feel better now
Thank you Starson. After some trial and error I managed to get rid of the offending text. I still seem to have extra page-breaks where the text was, but I can live with that. Great!
dwanthny, thank you too, I get the gist of what you're saying although I don't follow completely. Notepad++ must be a PC application? Anyway, I will go with your advice and use the method that Starson provided the link for; I have made a note of it for future reference.
All this trial and error with Calibre has made me realize there is a lot of power hidden underneath its uncluttered-looking bonnet. Very nice software.
