I right-clicked on the bear-off tray, trying to remove all four pieces fom
the five-point. This seems a reasonable extension of right-clicking on a
point to make it, and I'm sure JF wrks this way.

Instead, right-clicking causes an O chequer to appear briefly on the bar and
the O chequer on 20 to flicker. (Try right-clicking several times rapidly to
see it.) I'm wondering if this is related to the other artefacts I'm seeing.
