I don't think this bug has anything to do with the string being examined. It has to do with the first argument...cSearchExpression...you are talking about the second argument (cExpressionSearched).

Your example uses 'Q' as the first argument, that is only one character long. (Hey mom, look, I can count to one!!! *grin*)
