If I am starting to type an answer and copy/paste some MathJax from the question, I often get the error message saying I have to have 30 characters in my answer and I only have xx. I haven't asked to post the answer yet, and don't intend to until I have well more than 30. Can this be fixed?
Added: It seems to come up any time I have started to type an answer and click away for some reason. It can be to visit another web page, to copy something (doesn't have to be MathJax), or whatever. I haven't tried to post the answer yet-usually I am in the process of composing it.
