Seems, between Panic and you registering their own UTIs for SQL files, the OS
gets confused which is the actual type. AFAIK Apple assumes there is only one
UTI for a type. So when it opens the file, it sees your app can do the
extension, but when then looking up the UTI to go with that extension, it gives
you Panic's UTI because it doesn't remember which of the registered UTIs was
yours. Could that be it? I guess what you could do is try to register for
Panic's UTI as well (and that of any other app that declares one for SQL
files), then just internally map them all to your SQL document class?
