Hi Kovid,
Yeah - that's what's so strange. For a few years I've been using the same program, PDF X-Change Editor, and good old Calibre. Always worked before. Only just started to have this margins issue.
Like, just now, used
http://www.gutenberg.org/ebooks/730
and convereted to MOBI to PDF. Same thing.
Which is what's so confusing. It used to work. For several years. Is there any change to Calibre you can think of that could be influencing this? Or, any setting I may have inadvertently altered?
Sincerely,
Blain
