It started happening with Logos 4. I believe it began when our System Admin installed some Windows 7 updates. Thinking it was Logos 4, I updated to Logos 5 and it still happens. I can start it, run it for a while and there isn't anything really consistent about it, but eventually the mouse stops responding and a few seconds later it reboots. I've included the log file. Thanks so much, I really do enjoy the software.
Maranatha!
