Working so far for me, although I think there might be a hang-up between 10.3.4 and the Paranoid Android utility from Unsanity. After reboot, the installer (presumably) was cleaning up stuff in the background and it caused both PA and ShapeShifter to pop up warnings, which in turn locked my Wacom mouse.
I had to plug in the optical mouse in order to dismiss the dialogs. We'll see if it happens again when I restart / boot up next time.
...into the light of a dark black night.
