My bad, I jumped the gun on that one.
It looks like the control will sense if the underlying provider required a question and answer. So, have you tried disabling it in the web.config?
<add
name="AspNetSqlMembershipProvider"
type="System.Web.Security.SqlMembershipProvider, ..."
connectionStringName="LocalSqlServer"
enablePasswordRetrieval="false"
enablePasswordReset="true"
**requiresQuestionAndAnswer="false"**
applicationName="/"
requiresUniqueEmail="false"
passwordFormat="Hashed"
maxInvalidPasswordAttempts="5"
minRequiredPasswordLength="7"
minRequiredNonalphanumericCharacters="1"
passwordAttemptWindow="10"
passwordStrengthRegularExpression=""
/>
Wrong answer below:
Set the QuestionAndAnswerRequired property to false.
