I was running the above search this morning and Logos crashed.
These the logs from the time of the crash:
7026.Logos.log
7220.LogosCrash.txt
1033.LogosError.log
These are two other logs generated today that are probably not relevant (but contain errors):
8865.cef.log
6708.LogosIndexer.log
From the DigitalLibraryInstall.log (2 days ago), the only error line I found is this one (probably not related to the crash):
File: C:\Users\Rich\AppData\Local\Logos4\System\Logos.ErrorReporting.dll; Overwrite; Won't patch; Existing file is a lower version
(No errors in the LogosSetup.log)
