The toolbar button are not all actively usable. And Menu selections either.
How do I make them workable? I want to customize but also general usage for
example Print Preview, copy, and more. Just knowing the basics to get
started.

I am using Excel 2003. I just finished a one day course at the Library, but
the buttons on the installed version of Excell 2002 were already working. My
home computer needs changes..
