Dear Group,

Previously I have described a "feature" of publisher where it positions some
 elements
in units of points, and other elements in units of pixels. This leads to con
siderable issues
with formatting when viewing the webpage on a monitor that has a different s
caling
between points and pixels than the microsoft default. This program can be us
ed as
a post processor to convert all positions specified in pixels to points. It 
works well
for me and my webpages. Feel free to distributed it if you see fit.

Regards,
Mike
