I can only go back one page when using IE and that is only if I use the string of arrows above the AB logo. Fortunately, the default Browser on my Desktop computer is Firefox 8 and I do not have the difficulty of going back pages; but I do have the problem with FF7.0.1 on my laptop.
It is still my opinion that AB has a Server Error and I am open to my view be proved wrong . However, not a single Techie has disputed my way of thinking.:-

Incidentally, AB appears to be further malfunctioning today. Speed is slow and once came to an almost full stop.
