Lately, whenever I start a new file and type a number or date in a cell with
a single digit 6, it shows as the letter s, for example 6/6/2006 shows as
s/s/2006. If I preceed the number with a zero or in a multiple digit number,
it shows as a regular 6.
I have tried to change it using formatting the cell, but it does not change
it. Can any one help.

Thank you.
