Logos crashed unexpectedly. I had a number of tabs open and had clicked a Bible Reference. The Bible opened and then the program crashed.
Here are the logs.
7357.LogosError.log
7416.LogosCrash.txt
5556.Logos.log
Another instance of the Error 1887 History Manager crash.
This is the same error reported here: http://community.logos.com/forums/t/63286.aspx
Please see that thread for updates.
