It will do: that wasn't my picture. Chris G did the version in the picture,
but then never submitted his changes to the source. I did my version
separately, but didn't commit it until after the screenshot was posted
(because I was still wrestling with Git). The sense of our switches is
different, too, as I went for the "disable" logic of the rest of the
"Content Blocking" box but Chris went for "enable".

Are you using a build which contains JS? It works fine in a "json" build,
but in a "jsoff" version it gets saved (look in the Choices) file, then lost
on loading. However, I suspect that it's getting loaded and then overwritten
to false by the dummy js_initialise() in javascript/none.c (which presumably
isn't an issue in a build that actually contains JavaScript).

You can see what choices are getting loaded underneath the RISC OS GUI by
browsing to about:config and looking at the settings. As an aside, string
display on that screen probably wants to entity-ise any <'s and >'s (and
possibly other stuff too): it doesn't handle "<Choices$Write>.WWW..." in the
RISC OS settings very cleverly at the moment!
