Cross-browser printing iframe content

I found problem with printing iframe content in Opera. So here is my simple solution:

function print_iframe(s) {
 var iframe = window.frames[s];

 if(navigator.userAgent.indexOf("Opera") == -1) {
   iframe.focus();
   iframe.print();
 } else {
   var opera = window.open(iframe.location);
   opera.opener.focus();
   opera.print();
   opera.close();
   opera = null;
 }
}

I have been playing a Light Bot game. This game is very good for thinking and very funny. The solution which I founded for all twelve levels is here. Used actions are Move, Jump, Light, Turn Right, Turn Left and F1 for function macro number one, and F2 for function macro number 2.

BBC Learning English Support Material

In my opinion, the best Learning English site is BBC. But unfortunately for some reason the link to support material is not available on the BBC Learning English home page, now. So, link for this materials (Study guides and Worksheets) is here. Enjoy it, and improve your English, to be better and better.
