I'm using Chrome on a Mac and moving items into the correct columns simply doesn't work.
When I use the move button, sometimes the correct item moves (as per your documentation) and sometimes everything moves. Even when I get close to getting what i want, when I save the menu, another arrangement completely is saved.
Right-click dragging isn't working at all and what should be a 2 minutes job is taking a long time in what has become simply trials and error.
Is it possible to just jump into the database and arrange the menu items or is there a fix you can help me with?
