On our event registration form, where a user can register someone other than themselves. When they select 'Yes' to register someone else, a field appears where they can search for the person they want to register. However, once 'Yes; is selected, the page automatically refreshes in about 3 seconds. After the page refreshes, the form goes back to the original view as if the user just opened the registration form.
This is the only field that is causing the page to refresh.
Any thoughts on why the page is automatically refreshing and how to correct it?
EDIT: We are using Civicrm 4.2.6 with Drupal 7.34
