Here's a bit more:

I did this by clicking File > Save as... and then in the Save as... window I clicked Tools > General Options. Then I checked "Always create backup", clicked Okay and then clicked Save.

I understand that Office 2000 is old, but it works. (I use it because I don't care for the tool bar at the top of the later Office stuff that shows all the icons.

Thanks for replying, and maybe someone else who has and who uses Excel 2000 can step in and give me a hand??
