Problem: I have two computers, networked. Files are located on computer 1. Secretary can access and change those files on computer 2. I open word DOCUMENT on computer 1. type in some changes. move on to something else, without closing the document OR SAVING. Secretary at same time working in same file, making changes. she SAVES her changes and goes to lunch. I come back to the document a little later, make a couple changes and SAVE AND CLOSE FILE. ISSUE: when I reopen, the changes made by secretary are gone. Any suggestions? is there a way to make it so only one computer can have a file open at any one time? Other?
