Office 2003 and Win XP;

I have a normal XLS file which runs hidden (Window-Hide). This file is run
from a toolbar. This hidden file does things to other files from the toolbar
and in the process some data gets written into the hidden file, but it is
only needed temporarily.

The hidden file is shared, so it is set to open read only by default using
file properties. Apparently, it is not possible to code this file so when a
user closes MS-Excel the hidden file will close itself without warnings,
without messages, and without saving? i.e. just drop dead, quietly?

I have tried all manner of the following in either and both the Before_Close
and Before_Save events:

Cancel = True
Application.EnableEvents = False
Application.DisplayAlerts = False
ThisWorkbook.Saved = True
ThisWorkbook.Close SaveChanges:= False

No matter what I try, I ALWAYS get the save file question. If not
impossible, please tell me how it can be done.

Thanks much in advance from a very frustrated user.
