User Defined Functions NOT recalculating
问题 I recently took a large, stable XLSM file, and split it apart into an XLAM and XLSX. Thousands of cells in the XLSX call (udfs) functions in the XLAM, and each such udf begins with the statement "Application.Volatile" (overkill, to force recalc). The XLSX will NOT recalc with F9 thru Ctrl-Alt-Shift F9, nor with Cell.Calculate thru Application.CalculateFull. The XLSX cells are simply "dead" ... but ... I can reawaken them one by one if I hit F2 to edit the formula and then hit ENTER. Cells
