Graham – The color does change as I scroll, but only the topmost number is red. All those below are black and stay black until the red one at the top is scrolled off. Then the next number down becomes red. Odd.
In order to get my tool to display the way I want it to, I sometimes use tabs and sometimes spaces. The different dates are different widths; some are single digit . . etc.. I only use the browser to get where I want to be quickly, then close it. But it didn't look like is does now before the update. No big deal.
