i would suspect it's some html code in the bristol.gs under your username but that's just a guess.
Pretty close. I referred the problem to the higher-up-the-totem-pole-folk and it turned out to be an HTML problem of our making but, apparently, associated with Alex's profile details. Fixed now so, hopefully, we won't see it again.
Re the thread, I'll run up a post in the next day or two to explain some stuff about the gradient thing which might help sort out some problems evident in a couple of posts.
