Again: Please Wait

Hi there,

another case of "please wait" and nothing happens. I searched the forums and could find a lot of threads, but with no answers except for installing the latest version of Community Surves and CoreJoomla Framework API Library. Which I did.
API: Version: 2.7.1
Component: 4.6.3

This is what I get on the console(?):

cj.surveys.min.js?v=4.6.3:86 Uncaught TypeError: form.find(...).sortable is not a function
    at Object.CjSurveyApi.loadResponsePageComponents (cj.surveys.min.js?v=4.6.3:86)
    at Object.CjSurveyApi.onAfterSaveResponse (cj.surveys.min.js?v=4.6.3:940)

    at Object.fireWith  (jquery-1.10.2.min.js:4)
    at k (jquery-1.10.2.min.js:6)
    at XMLHttpRequest.r (jquery-1.10.2.min.js:6)

I guess every site is a special case. Anybody here to help me out on this?

Thanks
