What is the "forbidden" colour picker mouse cursor for? By this I mean the cursor where the picker is joined by a crossed-out circle, the universal symbol for prohibition. There doesn't seem to be any situation in which the picker doesn't work (perhaps you could argue that its not working when the read-outs say N/A but then why have such a reading?) If there is a good reason for this cursor, is it OK to change it so that the picker remains the "hotspot" even when the forbidden icon appears, at the moment the behaviour is (try it) disconcerting.
