Hi Jerry.. Well, log level 10 certainly generates a LOT of information. :)

Since the log files and dump file is almost 7 MEG tarred and bzipped, I 
am putting it on my web server for you to grab. Here is the URL:


I had the client simply OPEN an AutoCad file, make a small change, and

Thank you for your time and effort on this. I anxiously look forward to 
your findings. I'd love to put this to rest for my client.

If you need ANYthing else, please ask.
