Richard, in 2002 I think, if you have and old version of excel you can use
the autosave addin from it, you may also want to take a look at an addin
from Jan Karel Pieterse called AutoSafe. It will not overwrite the existing
workbook when it saves. have a look at it here http://www.jkp-ads.com/Download.htm , look for AutoSafe.zip
