I see it quite differently, Walter. Software developers don't go back and
update all previous versions when the build a new feature in the latest
release. Similarly, when a car manufacturer develops a new and more
powerful engine, they don't come to your house and put a new engine in your
older model of the car.
Pack and Go will not be updated because it has been replaced with Package
for CD in PowerPoint 2003. If you want to use Pack and Go you get the old
Viewer. You don't have to upgrade to PowerPoint 2003 to make use of the new
Viewer, however. You can create your own CD or package and include the
files for the new Viewer. We also have a product that will do it for you -
