AJ and I _think_ we are talking about the same problem. We might not be, although the description of the symptoms, which we have discussed many times, seems to be the same. The underlying cause might not be the same. It might be the code, the compiler, the OS. We don't know, which is why we need some more evidence. It might be different causes for AJ and for me. What we do know is that we had a much better solution a while back.
