Shwaline,
Copying what? The entire file, text, something else? What is the file extension of the document being copied? Do you have Microsoft Word installed on your computer?
Whenever posting questions on these forums, please give us as much information as possible about your computer. Depending on your issue, we might need the operating system, processor speed, amount of RAM installed, brand name of the computer, (if there is one), and any EXACT error messages you are receiving, and in your case, the version of Microsoft Word that you are using. The more information you give us, the better informed our answer will be.
Hope this helps and let us know more.
