I’ve been using your software for the past couple years and since I’ve upgraded to OS10.7.5 it seems I’ve hit a dead end with the screen turning black every time I calibrate. I read that this was a problem had by other users back in August, but I thought the most recent patch code would fix, but it is still the same. Any idea on what the problem may be and when it will be fixed? I have many followers on my website wondering the same thing! Thanks!
