When do I answer the server verification question?

In the Server Verification bubble, VolleyWrite requires you to indicate whether the correct player has contacted the serve.  When the correct player contacts the serve, click the YES button ON CONTACT so you don’t get behind.

I recently observed someone who chose to answer the question after the point was awarded.  Unfortunately, she got behind, and recorded the score incorrectly and missed a substitution.  I helped her get back on track, but it could have been easily avoided.

Also, if you are not scoring with a touch screen, please use a mouse, because for most people, that is fastest.
