I have 3 users working on a series of linked Excel files all feeding to a
final output file (STRATEGY OUTCOME 2007 WIP.xls). The files are not shared.

Last night one of the user A had the final output file open (STRATEGY
OUTCOME 2007 WIP.xls) - she had full access. User B saved one of the "sub
files" (DRAFT MODEL 061107.xls) and closed it. When he then opened the Final
Output file (STRATEGY OUTCOME 2007 WIP.xls) - it had been overwritten by the
Sub File (DRAFT MODEL 061107.xls) .

As another user had the output file open (and was able to make changes and
save it) - how could this have happened ?
