We are facing the following issue in Excel 2007 in our circle:
1. After applying filter, when we are trying to cut or copy a particular section of the data, the entire data is getting copied.
2. We have installed Service pack 1 of office 2007 but still the issue persists.
3. In some files though after 3 or 4 trials copy of sectional data is successful.

Pls let us know if there is any solution to this problem.
