No, the users experiancing the loss are not being prompted and we have at
least two documented cases where the last user to make changes did not get
prompted for conflicts. I assume this means that no conflict existed? Anyway,
I think the other possibility is that since there is no real security
attached to the file anyone could save a local copy and then save over the
shared copy. The will not show up in Track Changes either )-:

Resolving conflicts When you save changes to a shared workbook, another
person who's currently editing the workbook might have saved changes to the same
cells. In this case, the changes conflict, and a conflict resolution dialog box
appears that allows you to decide whose changes to keep.

Perhaps users are ignoring this and saving just their own changes?
