Remove Security Question and Answer

What do I need to do to remove the question and answer from the createUserWizard?  I have already specified requiresQuestionAndAnswer="false"
in my web.config and when I remove the html elemets and try to create a user, it doesn't create it.  I am also trying to get the excpetion that comes back but I can't figure that out either.
In summary, 2 questions:
1) How to remove the question and answer from the CreateUserWizard?
2) How to catch exceptions from the CreateUserWizard control?
Do I need to implement my own Membership Provider for this to occur?  Right now I am just using the default.
Anyone know how to resolve this?  My search through the forums has come up kind of empty.
 Thanks, ...
