AnsPress 2.0 – Any one can select best answer

Hi,

I found that the user who posts an answer to a question can mark his own answer as best.
This does not work right after submitting the answer, clicking at that moment on the “Select Answer” button does nothing.
But after page refresh the user who posted the answer can select it as best answer.

Shouldn’t it be so that only the user who asked the question can select best answer?
