Windows 7 Back button works on its own

[JPR]

Brand new Windows 7 laptop, in IE 8 I cannot stay on a web page. Instead it is as if I've hit the back button and the previous page is loaded automatically. This happens within seconds.

If I then hit Forward it sometimes stays loaded but more often than not, goes back again.

How can I stop ths happening?

Another question is, do you have a Wireless keyboard and mouse with the browser functions on either of them?

I have a wireless keyboard kit and found that every now and then the browser would randomly go to full screen, as if F11 had been pressed
Replaced the batteries in the keyboard and all is fine now
