What's all this nonsense about clues? If people know something about a circuit, why don't they just say it?

They don't. That's the point.

It absolutely is. All your circuit has to do is mess up once, which it can do in real life, and it's hung in the latch state that I described.
If you know of a reason why it will recover, post it.

It was Jim that posted "VoltageIndicator_NoHang.pdf", and I showed him how it can indeed hang. Seemed like a reasonable thing to do.

Wrong. I'm here to talk about electronics, and share what I know.
Why are you here?

Perhaps you should demonstrate that it can get there; instead of assuming that is gets there in the first place.
You made the presumption that there is a path to that state, prove it.

how it
Error! Error! Error! You are here to brag and denigrate, it is a simple matter of track record. You never admit any imperfection; yet find flaws in everything and everyone.
Check your ego at the office please.
Other than that, you do discuss electronics, just you treat most everybody as your inferiors. Why don't you have the wit to get that?
To discuss electronic design, both give and receive.

Poke in a noise glitch, EMI or ESD or something, at just the right time, namely when the cap voltage is low. The Q1Q3 latch looks damned sensitive to me, right next to a 5KV pulse generator.
But the issue was whether it has a hang state at all - hence the file name - and it does.
If a circuit has a fatal hang state, the burden if proof is that it *impossible* to get into it. That's Jim's responsibility, not mine.

Not so. In this particular case, the HV LED indicator, the problem is sufficiently difficult that almost every proposed solution has had serious problems. My mosfet-bipolar Schmitt has only moderate problems.
There are lots of civil discussions going on here.
OK, take a shot at the blinker problem.

-- So now, instead of simply admitting to an error, - anathema to you - you move the goalposts, take the lesser of two weevils, and state that The Larkin Way is bothered by "only moderate problems", while that of the rabble is besieged by serious problems. That sounds pretty narcissistic / elitist to me.
