I took several pictures of the frozen screens with colored triangles, always different each time!! I have to reduce the window and open again to reset. Also, I have some AU plugins that have black screens, dut in my list and the are working. I paid for version 4 and 5 few months after with so many new features as there are issues!! But so bizarre, no problem with last versions 4 or 3 for that matter. I am very disappointed. It takes an new update quickly to fixe that!
