John,
You have multiple people telling you to first eliminate any possible
source of RF that may be causing the problem. This advice is based on a
history of seeing many users having the same issues you are, and then
finding that they're getting a leak into their cables, usually a USB
cable. You haven't told us whether or not you've eliminated RF as the
issue, but keep pointing toward the software.

Are you running Vista-64?
There are vast differences in these operating systems.
This thread reminds me of the saying when someone only has a hammer in
their toolbox.
Again, the OP should be read, understood, and answered.
I think some here think software is perfect; and all platforms produce
identical results.
I've posted a bug; plain and simple.

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.

<http://k9yc.com/GroundingAndAudio.pdf>
Or study N0AX's new ARRL book on the topic, which was
inspired by my tutorial, and to which I made many
contributions.
