When using the xlLastCell in VB it will go further than the last cell?

It has to do with the fact that I am putting stuff in and then deleting it. xlLastCell will go to where the end of the last cell where the information used to be that I had deleted was. If that makes since..

I have figured out that if I save the workbook it will update and then xlLastCell will work just fine.. The problem is, that when I use that, it slows down the execution of the macro tremendously..

Any ideas? Is there something else that will update the workbook besides Save?

Here is my code as of now, with the ActiveWorkbook.Save in there.

    Sheets("Pending Approvals").Select
    ActiveWorkbook.Save    
    Sheets("Blank Form").Select
    Application.CutCopyMode = False
    ActiveWorkbook.Save    
    Rows("1:65").Select
    Selection.COPY
    Sheets("Pending Approvals").Select
    Range("A1").Select
    ActiveCell.SpecialCells(xlLastCell).Select
    Cells(ActiveCell.Row + 1, 1).Activate
    ActiveSheet.Paste
    ActiveWindow.SmallScroll Down:=33

Thanks for the help!
