Hi Caleb,
yes, actually it is designed so. If a scripting component is intended to
let Office stay alive when the last UI-window has been closed, the
component has to register itself as a TerminateListener on the Desktop
object.
Please use the following link to read more about it:

Best regards,
Mikhail.

<[email protected]>Hi
We embed a writer instance inside a Delphi form. When another, external
open-office document is opened inside a separate instance of Writer, and
that window is closed, then our embedded instance is also closed. If two
External writer documents are opened in separate windows, closing one of
them does not close the other one. That is what we want also with ours.
It seems like the last instance of Writer kills the global Desktop instance
if it thinks that it is the last instance. Also, each instance of Writer
has all the other instances listed inside its "Window" menu, but our
embedded instance doesn't show there.
Below is the routine that does the embedding into a group box; what are we
doing wrong? I have a feeling it somehow has to do with us "registering"
with the global Desktop instance that we are currently connected.
