I am still getting the error now in Form Builder that states:
The WAFV_ShowIf script does not define the findServerBehaviors.
This occurs while inserting a form.
I also noticed that when installing or editing a captcha, when you check that you want a refresh image available and then later go back to edit the captcha, the dialog box does not show the check. So if you check it back again, it actually creates a second refresh. While this is minor, I think it was probably intended that the box would remain checked to indicate that the feature is activated.
