Hi Brian,
Thanks for the note. I'm dealing with RFBD books. These are audio files so
scanning ETC. shouldn't be an issue here.
Just to remind myself of the problem, I went to the same book this morning
to recheck. It acted properly. I could go to a page, and BP reported, after
reading a bit, the correct page.
So it's intermittent. I'll report again if it happens again.
Rusty

Hello Rusty. I was noticing the same thing this weekend, and think
I figured out what is going on. For reference, I was using daisy books from
Bookshare.org, and since I think the problem is with presentation, I think
that's important. What I've found is that, A: the way Bookshare books are
marked up with the daisy language is inconsistent, leading me to speculate
that this has to do with the fact that books are contributed by volunteers,
and that each volunteer has a slightly different way of scanning and marking
the text. B: For those books which do have clearly defined page numbers,
the Daisy markup only marks page boundaries for the Bookport on even
numbered pages, meaning the markings only tell you when you've flipped the
leaf of a book, not when you switched reading from the left to the right
side. It took me a little while to figure this out, but if you bounce up
and down on the 7 or 9 keys on the Bookport for a while, I'll bet you'll
find it's counting in pairs of pages, not singly as you would expect.
In any case, this isn't the fault of the bookport, but either the
lack of clarity in the Daisy format, the loss of information as it goes from
Daisy to RTF to indexed ASCII, or a combination of the three.
By the way, in case it wasn't clear, when you go to a specific "page
number" using the goto page number feature in the Bookport, you're really
going to the text marked by the Bookport transfer utility as being page X.
What basis that has on reality with respect to the actual book itself
depends on the accuracy of the mark up, the granularity of the indexing, and
the particular edition of the book you're reading. Think of it like you did
in the old days when you had the print page numbers versus the braille page
numbers in books.
