Grame, I noticed just now the presence of this workaround code putting my nose in argyll sources. But since scrutinizing too much people's code causes me big headaches, I didn't understand whether is it already active, or it will be in 1.3.3 or not. Interestingly enough, I noticed that your approach has some similarities to what I was suggesting. It would be interesting to test it to see how it performs... /&
