i have been playing with the nightly build of  12-06-008, when installed if from the .deb for gutsy the the 3dp externals worked perfectly and i spent a few hours playing with its possiblites..
 i shutdown and went home.. the next day.. i opened pd and the 3dp externals where no longer there...
 i unistalled and reinstalled.. and they are still not working anymore..
 why could this be?
