Is this still a problem?
Not sure how many out here are using V2002...
Is it just the org chart drawing that won't let you do a "save as"? Just out of curiousity, once it is saved, can you go to the location of the file, and rename it? If so, then, re-open it with Visio. Make some changes. Save. And also do Save As and a new name. Do all of those actions work properly?
