Some time ago I added a posting that had this effect. I had to get the web master to delete it which cleared the problem. I assume that a non printing character had got into the post when I did a paste. The origin “Unable to add posting” thread now also has the problem. As both threads have the mug advert at the end I think this post is probably the cause of the problem.
I have just noticed that with Firefox the picture of the mug is visible. With Internet explorer only the header line is visible with the autors name (Jacques Maurel)
