can only edit one list item

[RowlandCarson]

I find that I can only edit one position list item in a GPX file - typically by click-drag on the map pointer of the selected list item. Once I have done that, I cannot select another list item. Sometimes I find I can select & highlight another list item, but the map pointer remains at the edited item and does not appear at the newly-selected item. The only way out seems to be to save, then quit RouteConverter and restart it. After that I can again edit just 1 list item then have to save & quit again.

I am using a MacBook Pro (15" mid-2010) running El Capitan 10.11.6.

I get the same behaviour with the stable release (build 2.20.845) and the latest prerelease (build 2.21.864) of RouteConverter.

I am running Java 8 update 144.

Any suggestions or help?
