I am an Excel developer for engineering applications and create a wide range
of tools for use by many people. I recently bought Office 2000 and found what
for me is a serious problem. When only opening (not changing or even saving)
an Excel workbook in Excel 2000, Excel somehow tags the file as being Excel
2000, and subsequent openings by Excel 97 (which most all my users have)
results in the unacceptable behavior of being repeatedly told it is a later
version. I've found no workaround for this (trying unsuccessfully every way I
could conceive to save as a prior version) annoying behavior. Large files
have to be saved "all the time" and every time the warning window comes up
saying the same version message.
I think either there needs to be a fix for this or a workaround that allows
Excel 2000+ files to be truly saved as prior version files.
