Description
Tested on Opera 11.51 Windows 7. This works at IE 9 and Firefox 6.0.3 and Firefox 7.0.1 without problems.
$("input[name='bar']:checked") sometimes returns object with checked attribute set to false.
Clicking on disallow and allow radios sometimes did not change disable property.
How to reproduce bug: clicking on disallow and allow radios with rate 1 click per second. If disabling and enabling checkbox working then click on "Not interesting" radio (unchecked) and then continue clicking on disallow and allow radios.
How to not reproduce bug: click very slow rate (about 1 click per 10 seconds).
I do not know if this selector is invalid (it works in IE and Firefox) but I know how workaround this problem. Instead of $("input[name='bar']:checked") use $("input[name='bar']").filter(":checked")
Example code:
<!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <title></title> <script type='text/javascript' src='http://code.jquery.com/jquery-1.6.4.js'></script> <script type='text/javascript'> //<![CDATA[ $(document).ready(function() { function update() { var element = $("input[name='bar']:checked"); //BUGGY //var element = $("input[name='bar']").filter(":checked");//WORKING if (element.length==1&&!element[0].checked) { alert("Error"); } var value = element.val(); if (value == "disallow") { $("#some_checkbox").prop({ disabled: true }); } else { $("#some_checkbox").prop({ disabled: false }); } } update(); $("input[type='radio']").change(function() { update(); }); }); //]]> </script> </head> <body> <form action="" method="post"> <div> <input type="radio" name="foo" value="foo1" id="foo1" checked="checked"><label for="foo1">Not interesting 1</label><br> <input type="radio" name="foo" value="foo2" id="foo2"><label for="foo2">Not interesting 2</label><br> <input type="radio" name="bar" value="disallow" id="disallow" checked="checked"><label for="disallow">Disallow checkbox</label><br> <input type="radio" name="bar" value="allow" id="allow"><label for="allow">Allow checkbox</label><br> <input type="checkbox" id="some_checkbox" name="some_checkbox"><label for="some_checkbox">some checkbox</label> </div> </form> </body> </html>

Hey. I have the same problem. But I found another solution to it! Compare my two versions: http://jsfiddle.net/Lexx918/yzVfc/ (works!) http://jsfiddle.net/Lexx918/yzVfc/1/ (does not work) Different one (well, two) lines.
Works for me in Opera 11.51.
