Gonna give associator a try.
Meanwhile, I've fixed my BBEdit problem with this simple expedient: dropstuff the BBedit OS 9 version and delete the program. If "BBedit for Mac OS X" is the only bbedit app on your Mac OS X system, you no longer make/get files with classic icons that try to open the classic version. It saved me a lot of heartache.
I realized that I would never, ever boot into 9 again, ever, if I could help it. Annoying as Mac OS X can be sometimes, I'm happier in X than I ever was in 9. So why let a 9 vers. of bbedit pollute my primo system?
