Bill,
I ended up replying only to you. I am adding doing to the list now.
The stack and thread info I sent you earlier is when I open the config
window, select a new audio device, and click ok. The following info is when
I edit wsjtx.ini by hand, change the device names, run wsjtx and wait for a
TX cycle. The application crashes at the top of the minute at the start of
a TX cycle.
