If you want to restore the screen picture for the user after a macro has changed the window view, you can sometimes just activate the cell that was the active cell when the macro started. This is not always successful. The following example code will restore the window position just like it was when the macro started:

Dim aRow As Long, aColumn As Integer, aRange As String ' global variables

Sub RememberWindowPosition() ' run this before making changes
    With ActiveWindow
        aRow = .ScrollRow
        aColumn = .ScrollColumn
    End With
    aRange = Selection.Address
End Sub

Sub RestoreWindowPosition() ' run this to restore position in the window
    Range(aRange).Select
    With ActiveWindow
        .ScrollRow = aRow
        .ScrollColumn = aColumn
    End With
End Sub
