Can you prove that its not RF in the shack? If you can verify that RF
is not causing it then its a bug, otherwise, there is no issues with the
software in your case.

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 thus
far 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.
73's,

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.
