Ed,

The XLSTART folder was empty and there were no unusual add-ins running.
I imprted the color scheme by having the spreadsheet open at the same
time as another one that I downloaded from microsoft, and then simply
copying the colors from the microsoft sheet. I used the
tools->options->color tab->Copy colors from drop-down list. Now I am
stuck with that color scheme. I suppose I could manually change each
color, but I am more concerned with how it seems to be affecting other
spreadsheets.

Thanks for your help,

Jacob
