Right, that's the menu, I get it all the time both in Chrome and Safari. I'm also on iOS 7.1. I do press-and-hold for some time for the menu to appear, but that's to avoid other touch event side effects (such as dragging the wrong module). My racks were private when I noticed this, but I am not in a position to verify if this makes a difference. Good luck and thanks for digging in. Thanks as well for removing my fake rating.
