Webform capability issue with Chosen
I had a similar issue with a recent OpenAtrium update (2.50). Apparently Chosen changed how it gets applied to fields, and this caused it to be turned off for select fields. In my case, it was as simple as visiting admin/structure/types/manage/&lt;content-type&gt;/fields/&lt;field-name&gt; and setting the option "Apply Chosen to the select fields in this widget?" to "Apply." This is done on a field-by-field basis.
