Thank you! Look forward to it being released to production! Have a great day!

I found that the issue was something a newbie would face. By habit, from other programs, I 'left-clicked' when I was over the color I wanted. That screwed up the internal processing, which gave the issue I reported. It continues to do so with factory settings. But if I don't click then it works (just press 'S' and hover to the color, then release 'S'). Evidently, others aren't bothered by this, it just wasn't the standard I was used to. Maybe put some type of processing in for clicking, so the color selection is changed in that circumstance, without the weirdness I discovered.

and seen that relevant patch has not yet been committed...

Thank you for the pointer. It was a WaitForSingleObjectEx error in nvoglv64.DLL. Found the non-MS, official NVidia drivers on Acer's site and installed them instead of the one Windows installed when I did a clean install. Two tests couldn't duplicate the error, so it's not a Blender problem and you can close this.

(It should be supported. In addition to the example I referenced, here's an old YouTube vid showing it in action: https://www.youtube.com/watch?v=MixfsYOrSk8.)

Thank you. An issue that appears is when that is done the metaball of the palm area changes shape when the transforms are applied. Is there a workaround for that, or is it a bug? I don't really care at this point, because I've learned a bunch, and can make it work, but the perfectionist part of me is still a bit bothered.

is the result of the practical problem of mirroring any object that has a non-zero orientation (it can't be done in global space).

Thanks! Have a great one! (Whatever 'one' is that you want!)

So all of this is by design, yes

OK, have a basic hand done which brings up another bug. With the attached file I can't see any way to mirror the metaball assembly without having the individual metaballs weirdly rotated. All I'm trying to do is mirror it to make it into a left hand instead of a right hand. If they are solidified into real objects first, then they can be mirrored correctly, but that isn't the desire. It would be nice to be able to mirror it as a metaball assy, then pose it, then turn it into real objects, join them, remesh them, and start sculpting.

Fortunately, I had made a screen recording and was able to figure out what was happening on the scaling issue. It is real simple.

This is a limit...
