Is your worksheet protected?
Have you grouped a number of sheets together (does it show [Group] in the
title bar)?

I have one file in which the data filters are frozen, and none of the
functions on the data tab (i.e. sorting) are functioning.

All my other Excel files have full functionality.

What have I done to this file and how do I correct it?
