startAmps tore down and rebuilt every amplifier client on any settings
save, and closing a COM port makes the Windows driver drop DTR/RTS. On a
KPA500 those lines ARE the power switch — so 'save' meant 'amplifier off
twenty seconds later', exactly F1TPL's report, and the fix that held the
lines while OPEN couldn't survive a close. An amplifier whose config is
unchanged now keeps its running client across saves; the others still
rebuild.
Also: isolate on the FT Map panel — Leaflet's z-1000 panes were painting
over the menu bar and the Preferences dialog, as the grid map's own
comment warned.
