Open application when file double clicked

Yeah, I got that stack and it works for me too.  I actually removed the
file association since that's how my app is built but it still worked.  As
mentioned previously, I'm thinking that perhaps the problem is in the code
in my startup/preOpenCard handlers somehow stepping on the appleEvent
message.  Since double clicking a file works OK for me when the app is
already open, that hangs together.
