1. In the GroupBox’s template find border with a multibinding on its OpacityMask and apply a IsHitTestVisible=”false” on it.
2. Order the content presenter over this border (with the multibinding).

The issue is that the content presenter is actually under a border with an opacity mask. Now, for some reason, the opacity mask still catches the hit thus preventing the underlying button (or any control as a matter of fact) to catch the hit.

Still occurs with WPF4.

If I move the mouse cursor to the top or bottom part of the button, it gets focus and can be clicked. Do you have a way to fix this problem?
