I have a fresh WordPress 3.5 install with Gravity Forms 1.6.10.1.
When I create or edit a form, many of the buttons that add fields are broken (clicking them does nothing). SOME still work, but the following are broken:
==Standard Fields==
Single Line Text
Paragraph
Hidden
==Advanced Fields==
Name
Date
Time
Address
Email
List
==Post Fields==
ALL OF THEM
This is a big deal. Gravity Forms is unusably broken right now.
