Chris is an Adobe engineer. He's also a person with a history of being abrasive and of refusing to admit he's made a mistake; he used to be a regular poster on the Usenet newsgroup comp.graphics.apps.photoshop, even before he worked for Adobe. It surprises me not one bit that he would maintain in the face of any evidence whatsoever that the problem was not with Adobe.
You're welcome to post a link to this thread on the Adobe forum, though I doubt it will do much good.
