I have a Dell Studio 1558 with Windows 7 Home Edition 64 bit. For some unknown reason my cut and paste functions are not working consistently.
Control C and Control V are working sporadically and I'm having the same problem with right clicking and choosing the copy and paste functions. If I click "cut" the text disappears but I can't paste it anywhere.
I've searched online for a solution and completed various diagnostics and can't figure this out.
What can I do to restore these functions?
