I take an orbit view and drop it onto a canvas. In the inspector, with alpha view, there is no arrow to show the controls. If I click on the user object in the list (descendents) then the arrow shows up.
Can't reproduce, at least as of 8b346bc. Some of the relevant code was rewritten for #173
Note that after #173, "control arrow" has been replaced by "settings button" (the little gear icon)
