I'm getting started trying to use NGUI in my projects, have watched the video tutorials (which are really nice btw), but when I drag and drop some of the example GUI prefabs into my scene, they are unresponsive to the mouse - invisible to the camera (which is running in debug mode).
I checked the FAQ for this, and it mentions the physics raycast hit trigger setting, which was already set. But am curious as to what the next step in debugging this now is.
www.blueomega.me/StrangeNGUI.mov is a demo of me trying to click on some of these NGUI elements.
