Thanks Karl, that's a clever way of doing it, but not quite what I was
looking for. (Mind you, it's actually very difficult to describe what
I'm looking for without either sending a series of images or some kind
of design structure, and the Rolodex is very much Gonzo coding: totally
unplanned, unstructured and driven by inspiration, happenstance and the
need for discovery and playfullness.;-)

Ned's line:

World allMorphsDo: [ :ea | (ea isKindOf: WorldTimeMorph) ifTrue: [ ea
delete ]]

Works a treat and it'll enable me to run everything from the dial...
buttons (I think). I'll let you know when I've re-written the tests!

Thanks again

Cheers

John
