This should not happen if you do NOT save the original file...

Try this
Open a file
Do SAVE AS to a new name
Check the time stamp on the original file
Does it change?

When I open a file that I previously created in Excel, then I choose Save As
to make a copy of the file the date stamp on the original and new file
reflect the current date. Is there a new service release that prevents this
from happening?
