Please post as a bug. I'll start investigating.
Enter as much information as possible including environment (version, os, etc) and error message (which you have done beautifully). If you can possibly send 24 hours of your log.nsf file, I will accept it support(at)startingblockcomputing.com. If it's the 24 hours that triggered the error, that would be great.
Thank you for reporting this. A fix will be investigated as soon as possible.
