I am getting the same error as themadness. When I try to
edit a page element a gray overlay appears and I am unable to
click on anything. If you click, the gray overlay disappears,
but so do the options.
The copy/move feature should be working. When you click it, this
window pops up: http://d.pr/i/1j1A1 From there, you
can choose which slider you copy or move to.
