If you lose the USB connection all bets are off.When you kill the process are
you killing wsjtx.exe and jt9.exe?
You should not need a reboot but perhaps Vista is a bit pickier about USB
devices that disappear and is causing the lockup.You can test that idea by just
pulling the USB while it's running. You should get an error and be able to quit
politely on the CAT control. But if the sound disappears that might be
different.
I haven't heard of any Vista systems on this list so you are kind of
on-your-own there. I see XP, Windows 7, and Windows 10, but no Windows Vista
or 8.

OK, so we're 100% clear - and I want this bug report to be that:
RF is causing the WSJT-X thread to hang in such a way it cannot be killed on my
Vista-64 machine?
Is that the claim?

Nobody is claiming hamlib is bug-free. But the problem you are reporting has
occurred to LOTS of people and the problem is almost always the same...RF in
the shack and on the lines.
You'll find your problem is band-specific. Transmitting 0W never fails.
Transmitting into a dummy load never fails. All of that will prove it is RF.
As Jim said, grounding can be an issue too. Many ops have improper grounding
(namely a rod stuck in the ground outside their shack which is not bonded to
the house ground).

Jim,
OK - so the claim I'm reading here is Hamlib is 1000% bug-free regarding
Vista-64? I'm very skeptical about that; the most obvious issue and nothing
mentioned thusfar obviates this.
I'm looking into the obvious first. If my rig was so poorly configured; how in
the world did I make a contact with Argentina?
And, I've made a lot of other contacts. Including Virginia, North Carolina,
New York, and North Dakota not to mention Japan. And Arizona, and California,
and Oregon, and Washington...
Since the thread running WSJT-X can't be killed; I'm looking into that first;
and the cause of that.
The next obvious step for me is to make builds myself and look into the source
code.

That's an interesting hypothesis. Since USB is differential signaling - it has
some noise immunity; but I will definitely check into this.
Hum/buzz gets into our systems as a result of failure to implement proper
bonding between interconnected equipment, combined with improper termination of
shields within equipment by their designers. Study my tutorial on this, which
goes through both circuit analysis of the problem and details good engineering
practice.

Or study N0AX's new ARRL book on the topic, which was inspired by my tutorial,
and to which I made many contributions.
