Commerce Kickstart facets get temporarily disabled (showing reduced opacity) after selecting one of them until the new search downloads. This is a cool feature. However, if the user clicks the browser's back button after that, then the previous page is displayed without reloading and the facets are still disabled, therefore making a new search impossible unless the user manually reloads the page.
In order to reproduce this problem, just visit KickStart Demo (http://demo.commerceguys.com/products), select a facet term, wait until the search is loaded and then go back.
What's the easiest way to solve this? I've been thinking of forcing a page reload in search pages or to use jQuery to make sure that all facets are enabled. Neither of them sound very natural.
Thanks for you answers! David
