Cannot delete GH components with the delete button in El Capitan

Hi,

first of all, thanks for the great work! the announcement really made my day

I have a issue with the delete button. When I select a component and hit delete, it isn’t removed from the canvas. I do hear a sound similar to the OSX error sound.
