Thanks for the prompt reply.
I've already got Speed Graph set to yes.
But I've also upgraded to 10.57 which might have changed the default?
I'll check again at the weekend.
The green box wasn't intuitive to me.
Green normally means you've got it right.
I know I was below optimum because of my buddy.
There appear to be a number of new settings, some of which I can't work out what they mean.
Is there a doc revision planned?
Otherwise I'll need to keep asking dumb questions.
