I'm creating a rather involved 3-page form allowing a user to create their own custom bed. Page 2 of the form involves the user selecting side cabinets. After making a radiobox selection (yes/no) for the "Left Side Cabinet", Wordpress or Gravity Forms is locking up the browser. In Chrome, it never recovers. If using Firefox, it takes 30-60 seconds and then it allows the user to move on. If you then attempt to change that radiobox field again it will again lock up the browser.
I have tried disabling my theme and all plugins. I have also tested the form via the form's preview option. None of these changes made a difference.
This is a rather large form with quite a number of html elements and images. I'm wondering if I'm pushing the boundaries of this plugin or is it possible there is a bug somewhere in my form that could be causing this lockup? How can I debug this?
Here is the temporary URL for the form:
I can provide the xml export of the form too if needed.
