Same for me too. I can drag to the left and right to create siblings (nesting) of the item directly above, but cannot reorder by dragging and dropping horizontally.
iCafe Library 1.7
Wordpress 3.6.1
Mindstream Theme on Genesis Framework
Browser: Safari 6.0.5 (doesn’t work in latest version of Firefox either)
Mac OS 10.8.4
I really hope there is a fix as I love what this plugin does.
