Orbit stops when mouse is over button

Hi,

I use wordpress for building websites and more specific Slider Revolution, if you are not familliar with that, you can stack elements and position them as you wish, So with the Clasic example swiss knife, i entered 2 buttons (fold and unfold) set them an ID so i can use them to puzzles, inserted the iframe of Verge to the scene, and everything works fine.

Except, that when i am orbit to the 3d space around the knife by holding down the Left click of the mouse, and the mouse passes over the buttons, the orbit stops. How can i prevent that?

thanks
