Fixed? (may need to refresh that page since it caches for a day I think)

yup - works again; thanks!

The iframe's width is about 10px too low. Instead of setting a specific width in the iframe, you can just change the value to 100%. this seems to fix it for me.

this jQuery should fix

1. $('iframe[src^="http://duckduckgo"]').css('width','100%');

- hope it helps

I know in the scheme of things its probably a low priority issue; but I just wanted to bump this because it is still not fixed and even though I don't actually use this personally I find this error annoying for some reason.

Looking at the code quickly it seems the root of the problem is the base width of 48px; which is 10px to short,Here is my solution.

In the new_code function, these lines:

1. width = 398;
   if (new_code_width) width=parseInt(new_code_width)+48;
   if (new_code_duck=='yes') width+=75;
   else if (new_code_duck=='small') width+=34

should be replaced with these

1. width = 408; /* This corrects the default value */
   if (new_code_width) width=parseInt(new_code_width) + 58; /* +10px to base */
   if (new_code_duck=='yes') width+=75;
   else if (new_code_duck=='small') width+=34; //no longer implemented?

or alternatively these:

1.   width = (!new_code_width) ? 408 : parseInt(new_code_width) + 58;
     width = width + ((new_code_duck==='yes') ? 75 : 0);

This last change isn't required, but will if the user has js disabled their width defaults to 550px which is to large.

1. <pre id="code">&lt;iframe src="http://duckduckgo.com/search.html?prefill=Search DuckDuckGo" style="overflow:hidden;margin:0;padding:0;width:408px;height:40px;" frameborder="0"&gt;&lt;/iframe&gt;</pre>
   

on side note.. which can probably be ignored.. not sure if this was done intentionally but 'width' is never declared locally (first line of new_code()); I couldn't see a reason why you would need to attach it to the window object, although completely unnecessary I would change it so its declared locally which is better and will prevent a strict JavaScript warning from being generated.
