Help: Screen space canvas on top of world space canvas (event problem)

In my scene I have a HUD and a simulated computer screen.
The HUD uses a canvas in screen space and the simulated screen uses a canvas in world space.

Now when a button in the HUD is over the computer screen it doesn’t receive ani mouse events anymore.

Is this a bug or do I do something wrong?

version?

Version 4.6.1f1

there were some issues with event ordering in that version you need one of the patch releases. (likely the most recent would be best)

Thanks I will update right away.

UPDATE: that did the trick!
