A patch that plays random audio files and video files crashes when I change audio buffer. Not only does it crash, PD wont start at all. And my CPU goes to the roof until I force quit in the activity monitor.

This happened yesterday on my one year old iMac and today on my MacBook Pro. Both on Mountain Lion. Same patch - same symptom.

I have tried to reinstall PD, but the issue remains the same. Any clues?

I am running the latest PD - Extended.

PD vanilla starts up without any issues. I have previously changed audio buffer settings without problems in PD - Extended by the way.
