Forgive me if this is not the correct group for this problem; if it
isn't please tell me where to go.

I have been using a particular spreadsheet for 3-4 years and was able to
enter integers into a column of cells, and having formatted the cells as
numbers having no decimal place have them show as integers and behave as
integers in formulae.

Some weeks ago for reasons entirely unknown to me Excel insists on
dividing the numbers by 100 so that e.g. 1 becomes 0.01; it shows as 0
if I format the cell as an integer but acts like a 0.01 in formulae.
Excel also does this in new spreadsheets.

I have noticed some weird things about this problem, in particular that
the same spreadsheet run on another computer behaves the way it was
originally designed to - i.e, when I enter 1 I get 1. The problem is
not present when I run Excel in safe mode or when I run Windows XP in
safe mode, but it is very inconvenient to run Excel in safe mode and I
shouldn't have to anyway. I have checked for add-ons for Excel but they
there don't seem to be any.

I don't get the problem when I run the spreadsheet under OpenOffice Calc
as an Excel program, but I'd like to be able to run it under Excel.

Can anyone help please or point me to a document in the Microsoft labyrinth?
