SyntaxHighlighter problems with jQuery 1.7.1

Recently I upgraded my WordPress plugins to jQuery version 1.7.1 and noticed that Internet Explorer 8 was causing errors “‘null’ is null or not an object”. I isolated this to the SyntaxHighlighter Evolved WordPress plugin I was also uses.

On further Googling it seemed that there were issues with the XRegExp library and jQuery 1.7.1, reported by other uses on IE 6 to 9. Schabse Laks posted a fix to the problem on his blog, though this gave me a new error, so I have modified it slightly, modification on line 271;

RegExp.prototype.exec = function (str) {
	if (typeof(str) !== "string")
		str = String(str);
	var match = real.exec.apply(this, arguments),
		name, r2;

    You sir are a genius. Keep up the good work. I was totally stumped until I read this post. Can’t understand why the latest version of SH is not working.
