I'm new to the whole text conversion conversation, although I promised I look around and read several threads before I decided to post this. I very much like Calibre and find it far superior to Sony's generic Reader Library.
All of the PDFs that I was able to send to my device while using the Sony software have reflowed just fine. Unfortunately, all the journal articles I've downloaded since switching to Calibre do not change display when I change font size. I realize that PDFs are WYSIWYG, but PDF articles form the same databases, same journals, same servers had previously been perfectly acceptable.
Is this a simple mistake on my part or am I doomed to either convert every PDF or switch back to that terribly unfriendly Sony software? Is this perhaps a problem with the software that first opens the files? What's changed?
