On some web pages e.g. Microsoft, Panasonic, Snowandrock, the product/service menu on the left hand side of the screen is not contained within a box. It is a list of words, some of which are superimposed over others, similar to a a set of transparancies, each of which has a single word thereon and then the transparancies are superimposed on top of one another with some words on top of another. If a product is highlighted another drop down menu appears and it overwrites the underlying picture/word.
Other websites e.g.amazon performs correctly.
