using the code ActiveSheet.Cells.SpecialCells(xlLastCell) normally works
fine. But, sometimes after working on a sheet for a while, the code returns
the address to cell IV65536 - the last cell in the sheet. I have tried Clear
= All from the unused columns and rows, deleting the unused columns and
rows, but once the sheet thinks IV65536 is the last cell, it is stuck. how
can I clear up the sheet, so it correctly calculates the last cell?
