Michael,

I second Ben's suggestion that at the least you should be using the File-

I've been looking at the problem of building a self-contained executable
inside a Wish Shell on-and-off for a couple months. It seems possible,
but currently tricky (in the sense of a series of tricks--not
particularly difficult, I think). The Wish dependence isn't going away
unless Pd chooses a different interface from Tk.

Whenever I quit Pd, I get a status message of "FWADisposeMIDIStream
result =" something. Do you? What does your something say? Is it
different when you File->Quit Pd from when you kill Pd less gracefully?

I've also head of bus errors occurring due to poorly written MIDI device
drivers for MacOSX. Check on your interface's manufacturer...

Cheers,
adam
