Hi Vic,
"Application.IgnoreRemoteRequests = True" will keep your instance private.
Be sure to set it back to False before you shut down that instance.
FWIW, that will only stop DDE requests (such as when launching a file from
Explorer), but won't stop OLE requests (such as when double-clicking an Excel
file embedded in a Word document or using any other application that uses
GetObject() to find a running instance of Excel to use.
