The website for dbMechanic doesn't mention that at all. It just says
to drop in those lines of code I quoted earlier and it's supposed to
"just work". However, your link does say to add that line so I did put
it in my dev.cfg file to no avail. I don't get it. I see people blog
about using it, but not how they get it to work.
Oh well. Thanks for the idea!
Mike
