Background: I was having the same issue with OS Sierra as many experienced back in '16, in that the program crashes when starting the finishing g code calculations. It seems like there isn’t a fix for it. So, I decided to jump into the V7 Beta.
Issue: The new V7 opens pop-up windows when using tools like ‘Define Stock’ or ‘Create Toolpath’, but when I select these the pop-up is just a blank window. Any fixes?
