I frequently find that If I am not very careful and click into the Edit text after each time clicking the Outline, the entire sections of the outline will be picked up and copied. So it is not possible to click multiple outline items without causing cut and paste of outline sections. This means that using the outline to navigate may (and frequently does) make permanent changes to the Text and the Outline. Secondly, once one of these cut-paste situations happens, Sermon Editor has no easy way to undo this - with a CNTL-Z or Undo option. Third, the Version History seems to be corrupted after this happens - so there is no means to walk back these unwanted changes to the Sermon. Once this happens, I can restore only by going into the text and copying the inappropriately moved sections back to their correct place in the text - this will restore the outline and the text (and the slides).
Once this has occurred, I find it necessary to restart Logos in CNTRL-C mode, to clear the cache, login fresh, and then the Sermon Editor is behaving correctly again.
This has been happening since back in version 9, through the upgrade to version 10, through to the 26.1 update, with all Windows up to date.
