Yeah, its looking pretty clearly tied to the MIDI stuff, especially  
since there have been recent changes to the OSX MIDI stuff.  Anyone  
want to file a bug report?

As for the -nogui thing, you need to have the standalone Wish Shell.app  
installed from


I use TclTkAqua-8.4.9.dmg.  And then you need to launch:  
"Pd.app/Contents/Resources/bin/pd -nogui".

If you are not part of the solution, you are part of the problem.
