actually
i had other issues of the page remembering where it was scrolled to when it was last visited.
eg. on the band site i'm designing,
if I was on the homepage, then scroll down half way and click the link in the menu to go to the "bio" page.
then scroll to a different position and navigate to a third page
if i return to the "bio" page the browser will always automatically scroll to half way down... basically whereever position it was in when that page was first visited.
crazy.
my interpretation of that line is
it is supposed to
find the awp_loop tag
then scroll up 100px
my work around is to change that negative 100
to some really huge number, -10000
so that it will always find the post, then scroll to the top
no matter where it thinks it's supposed to return to.
seems to work well
(I know this is probably poor practice... as it could break in a very large site, but it works well for me so far! *touches wood*)
also I think it fits with what my user would expect
As without AJAX, a user would be presented with the top of a new page upon clicking a nav link.
Hope this helps someone else out there!
shame this plugin is no longer supported by anyone
it's 2011 now and I'm yet to find another one that comes close
