Yes, they do .. Is this an unusual problem?
Well, it certainly shouldnt be happening :)
So as I understand:
2 PCs
each with a version of access and excel, both have the same versions.
the output file is from a mainframe and both PCs access the same copy of the output file.
The possible options I can think of are this:[list][list=a][*]Access Settings that are different[*]DB settings that are different[*]Excel settings that are different[*]PC settings that are different
If you open and close the file w/o making changes does it prompt for save, and if so what exactly is the dialogue in the notice?
Are both DBs running as the same version? i.e. both could be access 2003, but one DB could be in a 2000 format.
As a small test if you can, make a back up the DBs and place the backups on the other machines. This way we can determine whether its a Database based issue, or a machine based issue.
