WSJT-X/widegraph.cpp
Bill Somerville c05689944a Bugfixes:
Detector no longer collects samples when transmitting or not
monitoring. This was causingissues with the waterfall after tx periods
and was a waste of CPU cycles.

Correct the missing window title on the waterfall window.

Stop and restart the output audio stream if the configuration of
device or channels changes in the setup dialog. This defect was
causing spurious transmissions after changing configuration.
