This is a reposting of this problem, which is also in the ePub section,

but as more peeps visit here, I thought I'd try to catch the eye of an expert.

(She grovels).
When I load ePubs onto my Sony 505 and zoom the font to large, I get a narrow strip of text down the centre of the page and huge margins. I really hate this.
I'm not a techie, so if you do have any suggestions

please make them simple. On the other hand, if you have some really useful advice that really needs technical explanation I can always phone a friend who'll translate to Bookcat-speak.
