Frontscripts message path question

[Todd Geist]

Hello

I have a question about the the message path and FrontScripts.

Do Frontscripts sit at the front of the message path for all open
stacks or just the one that did the inserting in the first place.

Specifically,  I have a littl front script that keeps an eye on
another app and when it notices a change in that other app it sends a
message down the path.  Does that message touch all open stacks?

Thanks

Todd
