I just asked my first question. It received one answer, which was wrong (i.e. the suggested solution did not work when actually run). The answer has three upvotes. I've made a comment on the answer and also updated the question to clarify what I'm asking about (see Redrawing during drag-and-drop) and to indicate that the answer didn't work.
My question is: is there any way to indicate that the answer is wrong? I don't have enough rep to down vote yet and even then I think I could only down vote it once and the question would still be considered answered. I'm a bit frustrated as the question is now kind of lost in the ether as it is considered answered, when in fact it isn't.
