Hello.

When sorted by packet loss, the second sort column is DNS Name. If those are equal as well, then the sort order might change - it doesn't sort again by a third column. If you have blank DNS names (-------), try renaming them by right-clicking the target and selecting "Rename selected target." Once you have different names for the targets, the movement should stop.

The next release (due very soon now) will fix the ERR values so they sort after the highest latency, rather than before.

Best wishes,
Pete
