HI there
we seem to be having a problem in our environment whereby users are saving and opening files from a network share, the user works on the file but the links do not always update and when they do the changes are not saved to the original spreadsheet.
As this is our financial system the changes are quite significant, we also have a number of 0Kb files being created and these are not deleted after a user saves the file and closes.
Sometimes the file does not save at all and gives an error "unable to save" this is resolved by clsoing the application without an actual save being done.
