Ahh. A different question.
If you go into File|SaveAs|Tools|General options (xl2002+) wording, you can
check the "Always create backup" box.
But this is a workbook by workbook setting (different from MSWord).
You can create a workbook template that has this setting and use it as the basis
for any new workbook when you click on the New icon on the standard toolbar.
Start a new workbook
file|SaveAs|tools|general options (and check that box)
template (*.xlt)
and save it in your XLStart folder.
I hope you weren't too, er, what's that word... I'm sure you'll hear it from the
techie guy <vbg>.
