All - I've attached a testcase that shows that Webkit's JS engine is no longer properly processing '$$' when present in a replace() using a RegExp, where the replacement is a String (in Safari 3.2.X, this is working fine). Within the replacement String, '$' is used as a metacharacter along with a number or other special character to reference part of a match. Therefore, to output a '$', you need to use '$$'. This should output a single '$'. But in the latest Webkit builds (I'm using r40000), a '$$' is output when this syntax is used. All other browsers, FF 3.0.X, IE7+, Chrome properly process this (as does Safari as mentioned above). I've attached a small testcase. Cheers, - Bill
