Did you do anything to delete them? Have you tried a System Restore? Do the Windows defaults of Ctrl-c and Ctrl-v work? How about in other programs?
What happens if you create and log in with a new Windows User account?
First of all, thank you for a quick respond.
I don't remember to delete anything. Windows defaults of Ctrl-c and Ctrl-v don't work in InDesign, but work in other programs. I will try the System Restore and other information today.
