That's quite something, I'd've thought the I/O_Standby event was infallible!
Also there's no I/O poll from page 4, so your solution really feels mysterious (as well as fantastic!) to me ;-)

I was also under that impression for many years, and that after studying the code and also trying it out for a while. But the venerable HP-41 managed to prove me wrong here.

After fixing it with the quick page 4 hack, it was stable for 2 years. Unfortunately, the HP-41 I use for this has now managed to become somewhat glitchy recently, even with this hack. I do not know what is going on with it now. I hope it is the Clonix module in some way, but I have not had time to investigate it yet.

Well, if I ever find some spare time I will probably go back to this and a more proper page 4 solution, but it is really a lot of work and there is just too little time at the moment.
