To move the menu to your cursor, move to [[Cursor.X]], [[Cursor.Y]].
I figured out that showing the menu as a lightbox with a transparent background was the best way to make the menu go away if you clicked outside it. Hiding the menu on a page-level OnClick means you can't click any of the menu options.
Here's a partial solution. Works great in Chrome, but not Firefox or IE, because the interaction doesn't suppress those browsers' context menus. I hesitate to file this as a bug, because I'm not sure there's anything to be done about it, but since Axure reads these it has at least been raised.
