I'm working on a patch for a class project and up until a few hours ago everything was fine. I closed PD, then came back to it, but the file refuses to open. I get the "watch" symbol for a few minutes, then PD Quits all on its own. I can open larger files, and so far I've changed the file name, unistalled & reinstalled PD-Extended, restarted several times, and am pretty much out of ideas.

My computer seems to have become rather sluggish from this point on as well.
I'm using MAC OSX and the most recent edition of PD-Extended.

Any advice is appreciated...
