Views options in UI not working Options aren't working in my views UI.  JavaScript is enabled.  Example, if in views, if I want to re-write output, and I click the checkbox, I don't get more options.
I just had a similar issue (June 2014) with Views UI. The ajax interactions on the 'style settings' simply stopped working so click on 'customize field HTML' and nothing happened. Hence finding this post/tip. I went to the Modules/JQuery configurations screen (http://website.co.uk/#overlay=admin/config/development/jquery_update) and instructed the Admin Pages to use JQuery v 1.5 (instead of the current 1.10). All View UI interactions then worked fine again.

Adding this extra note for anyone that might find that handy. Thanks to Vintorg and other repliers for the solution.
