I think I'd just pepper my code with:

Debug.print application.screenupdating & "--Step ###"

Then run the code and see where it changed from false to true.

Maybe you have code that calls other code that toggles the screenupdating
setting. Maybe you're using a function that turns it off (often rare and I
think mostly from the analysis toolpak???).

Depending on what you find, it may mean that you can only add screenupdating =
false as soon as you see it toggled on (especially if you don't control the
other code).

Hi,
I've seen and religiously use the oft suggested technique to stop screen
flicker/refresh with running macros:
application.screenupdating=false
your code
application.screenupdating=true

I have one workbook, however, that merely switching between workbooks will
cause this workbook to redraw its selected sheet 3 times! Very annoying.

Could it be that its Workbook_Activate routine adds custom menus? Other
workbooks don't act that way even when menus are added. I've even gone so
far as to include all three:
Application.ScreenUpdating = False
Application.EnableEvents = False
Application.Calculation = xlCalculationManual

No change.
Can anyone shed light on this phenomenon, or offer a solution?
