OK… I reverted back to 9.6b4. Then I rebuilt all indexes, etc.
Things are working good again, now. I THINK I know what was going on…
I THINK adding the new 9.6b5 Smart Group rule “Days Since Start” (possibly “Days Since Start is 0”???) to an existing open/expanded Smart Group, or a new Smart Group that was open/expanded seemed to cause all my problems.
Ah!!! I had both of my Smart Groups containing the new “Days Since Start” rule “expanded/open”… And it seemed like some actions (Stop/Start/Relist) would change the contents of those “open” Smart Groups (adding new listings to the Smart Group during in the middle of the Stop/Start/Relist command) and the current selection would get “lost” and the action would get very confused and crash.
I had 2 expanded/open Smart Groups with the new “Days Since Start” rule that would get populated or de-populated during a Stop or Start or Relist operation which would change the listing ordinal order of the current selection.
