Or, more accurately, it (the pdf to speech program) couldn't decode it. I'll play around with this more tomorrow. The problem with a lot of this electronic paper is that the lines are sequeezed together. Makes scanning them that much more difficult. Last month I read a book [book-book, from the library!] with more ~1.5 spaces between lines, and even tho the font was small, no problem in reading the entire text. ((FWIW: I'll find the URL of a piece on Hegelian ethics --PDF-- and see if the firefox speech site can grok that!)) gary -- Gary Kline kline@thought.org http://www.thought.org Public Service Unix http://jottings.thought.org http://transfinite.thought.org The 2.23a release of Jottings: http://jottings.thought.org/index.php
