Recently I encountered copy/cut error in my excel tool. Actually it does not say error, it just don’t reflect the usual copy/cut thing. I mean when I click the copy button I was supposed to see a broken line on the four sides.
I just found out that the reason for this is the installation of Skype click to call. What I did was to uninstall the program and viola! my copy cut function is now working.
So if you are having the same problem as I was, try un-installing Skype click to call.
