"Not sure it really finds "bad" preference files."
I reserve my opinion on the value/pros of this programme.
In a lightning speed review it came up with a problem but did not show that problem in the listing.
I am somewhat skeptical that this application works with late 2009 edition of Mac Intel's. I ran PT to check and it found no problems although there were. When I trashed what i was sure was a bad preference all was OK with the application.
