Hello there,

thanks for those pointers but I have already done exactly what you
suggest:

(a) implement -application:openFile:
(b) modify GPSTextInfo.plist

No luck so far. I think Enrico's message documents the problem I'm
having.

In particular, I was able to duplicate the "gopen" behavior that he
describes:
