Hello Mike H and BJ,
The thing works normally in 'safe mode' but continues to fail in normal mode.
I looked at <tools<options<general on both startup types, both appear the
same. It looks like BJ is on the right track, although the problem persists.

This has just started. If I type the number 1 in any cell, it changes to a 2.
Also if I use -1
It is ok if I type, for example 21 or 10 or 111. Only if I use 1 by itself.
Microsoft Office 2003 Pro Windows XP SP2. Run two virus checkers, no
problems.
Please help.
