Stopping Form Field From Clear On Focus

When I create a CActiveForm (for User model), when going to user/update
the form textfields are cleared when I focus on them.

Can I stop this from happening with a setting somehow?

I really do not like this Drupal-like default behaviour - I'd prefer the entire textfield's text is selected instead, that way when I type it gets replaced or i can copy it or edit it ... alot more flexible.

Thanks in advance for any help!
