We moved all of our excel files from a peer to peer server to a shared
network drive. The drive is mapped to all of us as the "P" drive. We can
all open files fine.

However, when you go to save the file, you get the following:

The file xxx.xls may have been changed by another user since you last saved
it. In that case what do you want to do?

How do you get this to stop coming up?

Thanks so much.
