We have add-ins that sometimes require refreshing the data using the
parameters provided in the cells.
We have found that forcing Excel to recalculate with F9 (or
Alt-Shift-Ctrl-F9) will not force the formulas to recalculate.
However, using the Control-H (Replace = with = ) method works just fine.
Every cell is recalculated.

Is there any reason for this? Workbook settings are on automatic
calculations.

thanks,
Harry
