A family of Microsoft word processing software products for creating web, email, and print documents.
Here is the solution to your Copy - Paste nightmares.... The word software needs to be reset. Don't panic you won't lose your documents.
Step (1) Close all your open programs
Step (2) Open Finder
Step (3) Press and Hold Option button, then click GO on the top tool bar. Keep holding the Option button down and click on Library
Step (4) In the Library, click on Preferences
Step (5) Look for the file com.microsoft.word.plist
Step (6) Move the file to your desktop
Step (7) Close the Library file
Step (8) Open Word again, this will take you through a Welcome screen. Which means your word software is reset.
This fix has worked for me for over a week now and the Save button is thanking me! Keep the .plist file on your desktop, if something hits the fan you can always reset your settings.
Good luck fellow pasters!
