I'm guessing that because you are getting blank pages, you found the correct
button.
I'm going to gaze deep into my crystal ball and also suggest that you have
been bouncing this PPT back and forth between 2003 and 2007 versions of
PowerPoint. The way placeholders work in the two versions is very
different. The notes section is a placeholder and sometimes seems to get
lost when converting back and forth (even with the compatibility packs and
patches in place, even when down-saving). I would suggest sticking with one
version or another, but not bouncing between them for editing.
By the way, I just got my crystal ball back from the cleaners, so it might
not be your situation I was gazing into.
