Hi Rocio,

I haven't yet had a chance to test the example (it's holidays here :-)
but in principle it should be possible to use osgUI within a HUD as
well as in the 3D scene.  One of the motivations for developing osgUI
was the need to have a GUI in a 3D scene with full stereo rendering
(HMD's and powerwalls) so this is where I've done all the testing.

My best guess for why it isn't working in the HUD case is a precision
issue with the intersection routines. As a test try rotating the GUI
very slightly so it has some depth rather being planner.  If this gets
things working then we know that it's an issue with intersection tests
and these need to be adapted to handle the planar HUD case.
