I've got my Viewer program working now so that it will edit and save components. I would consider this still very buch a 'beta' Version so if anyones is wiling to test it out it would be great. So far there isn't much in the way of help files so hopefully you can figure it out. Some of the non-obvious features include; double clicking the pic file to select from the master pic that shows them all, right click on a field for help, and a few things such as the values for attributes have tool tips.
