I'd actually tried hanging a resistor across switched-live thinking
that might cure it and was quite surprised at the capacitor
suggestion, but it did the trick and the system's been sweet as a nut
since then. Odd thing is the system had been up and running happily
for a couple of years before the problem showed up (and it was one of
my installs so I'm pretty sure nothing had changed in that time).

Can you please explain "across switched live". What does the other side
connect to, and how does it fix the problem?

Connected across to neutral. The switched live stayed at 90V when the last
call was from the CH.

The cap that Geoff so kindly posted to me dropped the voltage to 3V
(readings made with a DVM) after the CH was no longer called for.

As to how it fixes the problem then you need Geoff or John to answer. It is
long time ago that I did electronics.
