Thank you! That was it.
I filled in the info and everyone was happy. This has to have happened as one of a couple of my fumbles making the upgrade to 295b4. Being sick and "medicated" is not the best time to juggle files.

Default Well, I give up

I have tried every combination of the params used to control hyperthreading & cores to get 1 worker using all cores with hyperthreading to no avail.
I have tried 3 different machines.
Yes, I scrub the directory clean between attempts ( except local.txt ) so it looks like a new install.
Can some kind soul please clue me in?
TIA

Memory bandwidth limited? The toy may actually do use all cores, but they each has own free time, caused by the fact that they can't get/send the data in time. How does task manager look like, are all cores busy x<100 percent, or are n<all cores busy 100% and the rest 0%?

There are at least 2 options, in local.txt assuming you have 4 physical cores and 8 threads with hyperthreading:
WorkerThreads=1
CoresPerTest=4
HyperthreadLL=1

OR

WorkerThreads=1
ThreadsPerTest=8

I was curious about this, so I set up an 8 core, 1 worker on the test version I keep. I mostly use this instance for torture testing. It is v295b4, like the working copy.

After creating the setup, I was too lazy to set up a worktodo.txt, so I ran a few seconds of Blend TT. When I checked back in Worker Windows, it had reverted to the 4 core settings, even though 'Use multi-threading' was still checked. I haven't tried anything more, but the result sounded similar to yours. 8 hyper-threaded cores, one worker settings revert to 4 cores, 1 worker.

Default Prime95 v29.4 b8

I see binaries for version b8 (e.g., Windows: 64-bit 29.4b8 - Released on: 2018-02-09), but there is only source code available up to b7. How can I get the source for b8?

You can't. It's been a long while, I suspect I did not upload new source because the difference was very minor.

Thanks ATH !
The first suggestion worked so I did not try the second.

To the others ( irowiki & LaurV )
Running Windoze.
I am running memory bandwidth tests, Laurv.
I'll report on these later.

I don't remember when (it was a recent version), prime95 Worker Windows dialog box changed from a "thread-centric" view to a "physical core-centric" view.

Take your 4 core hyperthreaded machine. The old prime95 let you allocate up to 8 threads among your workers. If you were smart enough to only assign 4 threads, then prime95 was smart enough to use different physical cores for each thread. The new prime95 interface lets you assign up to 4 physical cores to your workers with a separate checkbox for "use hyperthreading".

I think the new scheme is easier to understand, but the transition period may be confusing.
