I have a spreadsheet which has some formulas which do not refresh properly.

They are simple "IF" formulas.

If I press F9 or Options / Calculate Now, they do not refresh.

They only way I can get them to work is F2 when I'm on the cell (revealing
the formula in the Formula Line) and when it closes it refreshes.

I have this formula in other sheets in the same spreadsheet but I don't have
this problem.

Any ideas?

Thanks (and happy new year to all!)
