When I shutdown Windows (7) with Logos open, rather than Logos gracefully closing it reports an error - see screen shot. When I shut down Logos myself this error does not appear. Latest version of Logos (updated today).
We have an active case for this issue in Development. I will add a link to this thread to the case so that we will update you once this issue is fixed.
Thanks!
