I'm seeing RED all over too! The icons you used to be able to put on a thread when you created it are gone from the Full Reply page and all the existing ones are replaced by really ugly RED quote mark icons!
I'm also finding that my cursor vanishes a lot when making original post or editing it. I can click where I want to type or insert test, but no flashing bar to show where cursor actually is.
Thanks for reply - guess there's some bugs to be worked out - of course, not before release!
