Thanks, Jeff, for the advice on looking into notifications-email-procs, which I am now doing in some detail.
The thing is, when I consult the annotated current version of this file I see all sorts of changes in the areas that might matter. While I am ready to troubleshoot my existing code, I'm wondering if my time isn't better spent learning how to install and use CVS and then bringing my files up-to-date. Or is this is a no-brainer for those of you who are experienced developers and a lesson I have at this moment to learn?
