Yes, decoupling the instances means that I don't get the spinning beach ball when I try to save the file or delete a track in my arrange window. As I said before, the problem lessens the fewer coupled instances I have.
But that's not the point. If that just means that I have to decouple every instance of VE Pro every time I want to do something routine, like save my session or delete a track in the arrange window, that's not really a practical solution.
