We might need a few more clues:
What is in A1? What is in A2?

This is very strange...Excel does not calculate any formula. I can do a
simple =A1+A2, and it just return a zero value.

I made sure of the following:
- Cell is set to General (tried it with different cell settings too)
- Autocalc is on in settings (even a manual F9 calc doesn't work)
