I have 23 fields in my export view right now. I'm trying to add a few more but its non-responsive. When I click to add fields, i can choose the fields I want to add, then I click "Apply this display". The screen comes back and the button is then changed to "Add and configure fields". So far so good. Then when i click "Add and configure fields" the little drupal wheel comes up for about 1 second and then the wheel disappears and the screen never changes to go to the configure screen. I click it another dozen times or so thinking maybe the server just isn't responding quick enough. Nothing happens. I ran a test to add this same field on the regular view that the views_data_export is attached to - the screen view - and the field adds fine. Obviously adding fields of the views_data_export view has worked before because I already have 23 fields and have done this before. This problem just started today.

Any ideas? We are on Version 7.x-3.0-beta8.
