Hi Bill,

RFI may be a common cause, but not the only cause...

Recently, I had the waterfall freezing just 45 seconds after starting WSJT-X. Clicking the "Monitor" button once or twice showed the "Error in Sound Input" message. Needless to say, no transmission has been done during this time.

I believe an easy recovery from this error would be useful regardless of everyone's attempts to find and resolve the causes.
