Hi, Andy.  I'm fairly sure that the fault is mine.  I think I only downloaded 
the minute or two when I was trying to remember how to turn off recording :-)  
I've saved the whole log now.  I have to be out most of today, so it may be 
tomorrow before I get to it, but I'm betting that the output will be a great 
deal larger.  I'll let you know how it goes.
