Parallax & responsive mode bug report

Hi,

I found a bug in all the upfront child themes, when you make a region parallax and want to go to the responsive mode, and the "responsive" mode button (and the save button) doesn't respond. There is jquery error: uncaught Error: Can't call the method refresh. The object is not initialized

(tested it on all the themes)
WPMU 3.4.1
upfront 0.4
