It was only after posting that I found that. It was on the top one, "Show filled areas in zones", which sounds right. > Secondly, for a zone to fill it must have a net associated with it, and> there must be a pad or track within the zone area that is on the same > net.

Checking "properties" of the zone confirms that. The entire GND network, with through-hole pads, SMD pads, and a whole bunch of tracks is inside the zone. That's 17 pads and many tracks. (I'd connected them all, just in case the airwires had been the holdup.) The manual talks about segment fill, rather than polygon, being a safer bet, so I've just tried that, using the fill option after a right click on the zone edge. Still no visible fill. I think the window which flashes up is a progress bar. I had enabled use of graphic acceleration earlier. Kicad does appear to think it is rendering the fill. Does it do that concurrently with the progress display, or after? We must be narrowing the set of possible causes. How many can remain? Many thanks for taking a look at this peculiarity. Erik
