Thanks to MichelleC and Falkyrn for trying to help, but i think you may have misunderstood the problem.
I can normally surf the net without problems, but certain cites deliberatly lock you in to force you to click on an option that you do not wish to, when you then try to leave the site you are not able to use the back button or even close the page.
I see you have ticked this thread but hopefully you will read this .
I thought about this subject a little more and as i said above "It wont work every time unfortunately , as some sites are a little bit to crafty" , if the Windows key / D key does not work , another option and more likely to work is by using the ALT key and F4 key together , this should shut the offender off !
I also had a look on google and the popular name for a page with out a toolbar is "chromeless window" , if you want a better explanation of what can be done have a look click here .
