I recently installed Excel 2007 and notice that many of my files are
running
in Compatibility Mode. What does this mean and how do I stop it from
doing
that (if I even want to)?


Excel 2007 default file type is .xlsx - prior versions are .xls - when you
open an xls file in excel 2007, it runs in compatability mode (AFAIK....)
