Unusual Message when browsing

[Guest]

Hi. I have 'developed' a very unusual message when browsing with IE6. If I
type a new URL in the window at the top, rather than locate the site I get a
pop up window with the message "The Requested Lookup Key Was Not Found In Any
Active Activation Context" and thats it, nothing else. The same message
appears when I try any 'link' on a web page.
Any ideas? Many thanks
