Hi, i tried closing A360 but i didn't solve anything. It seems that the same problem of this thread: https://discussions.apple.com/thread/6295683
Even with the LT version is the same, and the problem is that of course even the drawing inside the application lags so i think i have to switch to parallels or something similar. I have to admit that i was very unlucky, i will wait for some news anyway!

Andrea.
