Application.screenupdating

I am working on BPC and have issue with the Flickering screen. This is basically the code that i have, The Application.screenupdating is being over ridden from a a BPC COde that I don't have any control over which is the "MNU_ETOOLS_EXPANDANDREFRESH", Is there another command that I can use to control the Screen Updation?.

Thank you very much in advanec for any help on this.

 Application.ScreenUpdating = False      

 Application.Run "MNU_ETOOLS_EXPANDANDREFRESH"

 Application.ScreenUpdating = True
