Please help, I'm not a techie, so be gentle with me.
I've noticed that when I put ePubs on my PRS 505 and set the font to large, I get huge margins and a narrow strip of text in a column down the middle of the reader. I've tried correcting this in Calibre, to no avail. I haven't got ADE, because for some odd reason, it won't work and has just given me more problems.
Is there a way round this, if so, please explain in language I don't have to google or phone a techie, non ereader, friend to translate to BookCat speak.
Thanks
