might be helpful. Your question is a little bit difficult to understand as it is posted. It sounds like your are trying to use some version of Microsoft Excel, but I'm not really sure what the master copy refers to; please post more specifics of the exact steps that you are performing and the program you are using when the problem occurs.

Copy and paste in vista shouldn't be any different than they were in XP. Alternatively, you might try posting to the Microsoft Office forum if your problem does involve Excel.
