bug: clicking one controller also acts as a trigger for the other controller

[kfarr]

As a user I use my left-hand controller laser pointer to select and trigger items on the menu hovering above my right-hand controller.

However, when I use my left-hand controller to press a next model button and if the right-hand controller is pointing at the city grid, then in addition to changing the currently selected model the model will also be placed.

Instead, if I click with the left controller on the next model button it should not also place an object on the grid.
