I've written some macros that copy and paste large amounts
of information, and when I delete a sheet, it gives me a
prompt to save the information on the clipboard.

On one computer, the commands:

Application.DisplayAlerts = False
....
Application.DisplayAlerts = True

work fine. On another one, though, it doesn't. I was
wondering if there's a different way of doing the same
thing, or why this might be happening. Thanks.
