It happens suddenly when I manually bang a matrice one or several times and use jit.print, and probably other objects.
Max totally slow down, even if no metro or any process is running.
I have to quit Max. Sometimes if I relaunch Max, nothing has changed, a simple "lock patcher" takes several seconds.
In these cases I relaunch my computer.
