I like the little bracket-like, tab-like border under each menu bar button. Is that new?
Now I see that it looks different in a forum, like interrupted black lines with a short cross bar like an upside-down Tee.
The tab-like border was visible when I was at the very top of the ATP home page. It seems that the border goes away and the thin black-line-with crossbar appears when I scroll.
Hmm, F5 makes the menu bar go away if I'm in the middle of a forum, (until I scroll again). But F5 does not make the menu bar disappear when I'm in the middle of the home page.
It's late - and I'm obsessing on minutia.
