From the Immediate window, you can type application.screenupdating = true
I have no idea about the donotpopulate as that is something I am unfamiliar
with. (Perhaps also from the immdiate window, but I wouldn't want to say.)
You could also run a macro. I saw this idea on (I believe) dailydoseofxcel
blog (dick's blog.) I think I copied this into my personal.xls. Let me
check ...

Public Sub ResetExcel()
On Error Resume Next
Application.EnableEvents = True
Application.StatusBar = False
Application.Calculation = xlAutomatic
Application.Cursor = xlDefault
Application.ReferenceStyle = xlA1
ActiveSheet.EnableSelection = xlNoRestrictions
ActiveSheet.ClearArrows
ActiveSheet.DisplayAutomaticPageBreaks = False
End Sub

Actually was not in personal.xls but I am putting it there now.

To improve performance, at the beginning of my macros, I do
DoNotPopulate = True
Application.ScreenUpdating = False
and restore these at the end. How do I manually re-enable excel sheet
operation if the macro fails before completion? Ctl-Brk or Run - Reset is no
help.
