Problem with new gui button rollover and click

Hello Unity Community!

I’ve got some problems with the new gui buttons, where the button does now work properly with the on rollover state, and also, does not “gets” mouse clicks.

On the image, the button should stay black on rollover.
I do know that I’m being a little vague, but is this a know issue? There is a ngui setup, a common 3d camera and the canvas is set up as Screen Space - Camera (using another camera).

Found the problem. My custom mouse arrow is blocking the raycast.
:frowning:

Problem that was solved adding a Canvas Group component to my custom mouse arrow. Then unselecting “Blocks Raycasts”.
