Gary, it doesn't have to be a recent change. In fact, Andy first sent me
a note saying that it seemed there is a bug in my CRC code, because it
rejected a job which looks just fine. One may not notice the uppercased
letters right away, and one may just think "Ah well, he must have typed
this from home and had problems with his modem" (or whatever). I would
not be surprised to hear this problem has been there for months, but was
never detected.
