TWO FAULTS, ONE SYMPTOM — 'it refreshes ten times a second and the
buttons cannot be pressed'.
Preferences is a child of the main view, so every cluster spot, CAT push
and decode re-rendered the entire panel. On a busy evening that is
several times a second, and the panel is large enough that the rebuild
outlasts the gap between them: buttons missed their clicks because the
element under the pointer was replaced between the press and the release.
It is memoised now, and the callbacks App hands it hold their identity —
without that the memo compares unequal every time and buys nothing.
The dropdown menu was an absolutely-positioned child, so it was clipped
by whichever scrolling or overflow-hidden box it sat in: the satellite
list showed one entry of eight. It is portalled to the body now,
positioned from the field's rectangle, re-measured while open, and opens
upward when the field is near the bottom of the screen — which is exactly
where these fields tend to be.
The RST comboboxes allowed free text, so a report typed by hand that isn't in
the mode's list (e.g. "600") was committed. Drop allowFreeText on the four RST
fields (QSO entry + edit modal) and make commit-on-type push a value only when
it's actually in the list; a leftover invalid entry reverts to the last valid
value on blur. Programmatically filled values (FT8 SNR over UDP, presets) are
unaffected — only manual typing is constrained.
