I went and looked at this at home at the two computers I have at home -- a downstairs lap top and an upstairs computer. And both this thread and my screenshot are charcoal grey on both.
Argh!!! I declare myself officially stymied!
Don't have an answer for you, Freezie. :( What's brown to Rus, Gabz, Lori, Temple, Wolfie and I looks to be grey to you, Dolly and dixie. It's brown on both mine, and of course the screenshot you sent looks just like "mine" - brown! LOL The mysteries of the world wide web. :)
