Thank you Ray, the find-and-replace did indeed work! I did a test on one server behavior first, and when that was OK, I replaced the whole shootin' match. Much obliged!
On a related question, because "No table found" was showing up in my Bindings panel, I thought I should do this in DW v. 6. But when I opened the same php files there, all server behaviors had disappeared! It was as if I had never written them - even though that's in fact where they were created. Any ideas as to why?
