Might be a systems glitch David. I recently sent a PM, and the person on the other end said that it was blank. After I typed it up again and resent it, he said that the first one had come in and it was all there.
This is why I hate computers and all things digital. I actually used to program computers (very simple things for medical surveys and the likes) and what infuriated me was when you would do everything right, and sometimes stuff just would not work. Go to lunch, come back, and it worked fine. Very epheremal sometimes, other times not.
