Morning all, so I've been alerted to this problem by a couple of my users.

They have a .xls file on a mapped network drive that has sharing and editing by multiple users enabled.

Recently they've noticed that when anyone opens the workbook, makes a change, and saves it. The updated workbook is saved as a .tmp file with an eight random character name while the original file remains in place without the edits.

This happens every time anyone saves the file and they are amassing tonnes of these tmp files.

I can't see what's causing it. Has anyone else come across this problem?
